Another player's outfit shows up when both of you are playing the same sex of character. On 2026-08-12, with one male and one female, the peer's body built wrong and no clothing appeared at all.

Played twice on 2026-08-12 with a male and a female character and it failed both ways: one player invisible, the other with the wrong head. The cause is now known and a fix is written, not yet played.

Tried in game on 2026-08-06 and the engine refuses to play it on another player's character. Parked for a later polish pass; a nametag already shows who is in their Pip-Boy.

Validated in game by owner report on 2026-08-03.

Read-only probe is built; occupancy, ownership, mirror suits and fusion-core sync are not.

Names, levels, health and rads render over peers; head-bone anchoring fixed height bob.

Validated in game by owner report on 2026-08-03.

Server routing and the Pip-Boy model writer are built; whether the icon appears is untested.

Health, rads and level are replayed on interest changes and resync periodically.

Validated in game by owner report on 2026-08-03.

Player shots are captured and replayed; dry-click shadow shots are fixed.

Validated in game by owner report on 2026-08-03.

Armed melee routes through the action path; unarmed replay is still unsafe and cosmetic only.

Input is distinguished, but the capture or proxy refusal path still needs a probe run.

Confirmed with two players on 2026-08-07: shooting another player hurts them. Before this, one player's gun could do nothing at all for a whole session.

Protocol and authority routing are built; the recent fix still needs a live validation pass.

NPC attacker damage is reported and applied to remote players.

Validated when the peer weapon equips; equipment gaps still gate some launches.

Replica damage is guarded so one blast is not reported once per observer.

Confirmed in game on 2026-08-08: a killing blow puts you down instead of killing you, and your teammates see it. Nothing decides yet what happens when the whole party is down at once.

Confirmed in game on 2026-08-08: after bleeding out you get back on your feet on solid ground a short walk from where you fell. The earlier run that left you hanging in the air is fixed.

Confirmed in game on 2026-08-08: a teammate can walk up to a downed player and bring them back. Charging a stimpak for it, and the pose the downed body holds, changed after that run and are untested.

Probe and target-fairness design exist; fair combat membership is still being built.

Settlers and companions defending every player is not implemented yet.

Connected-session suppression is built; it needs live validation.

Adoption of matching references works; spawning missing NPC replicas is still unexercised.

Template ancestry fallback is validated for adoption; true spawn cleanup is still open.

Quest alias actors now pose-sync, but the session will not kill or resurrect them.

Equipment rides roster entries and applies after 3D is ready; spawned presentation still needs coverage.

Roster condition sync is built for health and WorkshopActorWounded; not run in game.

Life-state apply for unconscious actors is built and idempotent; not yet validated.

NPC and turret gunfire relays as one burst message instead of one per round. Muzzle flash and sound on peers are not confirmed in game.

Owner-reported on 2026-08-07: a body can come to rest tens of metres from where the other player sees it. A fix landed the same day and it still drifts.

Owner-reported on 2026-08-07: what a body is carrying can differ between the two players. Not diagnosed yet.

Lost limbs, and bodies vaporised by energy weapons, are not carried to the other player. Gear on a body that was already dead only partly matches.

Validated in game by owner report on 2026-08-03.

No separate random-encounter system is planned; those actors should ride the ambient NPC roster.

The mod dismisses followers by default; recruited companion sync is not built.

A nametag names who is with that player, and another player's cell no longer drags your own companion around. Built, not yet validated in game.

The Lone Wanderer companion-global bridge is built; not validated in game.

Ordinary doors relay end to end. A door that loads a new area is deliberately left alone, because syncing one could hang the other player.

Two players walking into the same building together used to leave one of them stuck on a black screen. Fixed and confirmed in game on 2026-08-07.

Lock state converges through the world mutation path.

Open-state relays for ordinary world refs are validated.

The message and the server rule are built, but the allow list ships empty and the receiver does not replay yet, so nothing is shared in game today.

Server-created refs now enter open-state sync; flip-a-pylon validation is next.

Durable snapshots and transactions are server-owned.

Open container menus repaint when another player changes the contents.

Seeding unresolved leveled lists can publish generator forms; the safe baseline needs a live run.

Static placed loose-item removal is durable and replayed on cell entry.

Runtime object identity lets dropped items survive outside the first occupied cell.

Containers and dropped items now carry each item's attached mods, so a legendary weapon is not a plain one for everybody else. Built and merged, not yet seen in a live game.

Carried-object physics has the pause-resume fix from 2026-08-03.

Server save stores creations, removals, open state and container state.

Replay works after entry; the true pre-presentation load hook is still unidentified.

Respawn-cell contents are not reconciled yet.

Confirmed with two players on 2026-08-07: picking a plant shows for the other player. Settlement crops, and plants growing back, are not confirmed yet.

Cars are in sync while both players are there. Other breakable things, and anything destroyed before you arrive, are not confirmed yet.

Confirmed with two players on 2026-08-07: a car takes damage and blows up the same way for both of them.

Weather form and blend synchronize in game.

GameHour synchronization is validated in game.

GameDay, GameMonth and GameYear are not synchronized yet.

Deleted references are visible to world sync now, and a detonated mine is told apart from a disabled one. None of it has run in game, and mines a player throws are a separate path.

Quest-flagged refs are protected, but scripted event replication is not built.

Placement syncs in a live session, including objects across settlement cell boundaries.

Workshop-built objects and plugin-placed clutter scrap in sync.

Validated in game by owner report on 2026-08-03.

Linked ref and HandleCreation are built; generator-alone validation is next.

HandleCreation should reach the build budget and ratings; the effect is unvalidated.

Built to hide singleplayer-only builds that the server never saw; not run in game.

Partial in game: refs are named and tracked, but peer cable presentation is incomplete.

Partial in game: endpoints and spline params are tracked; power transfer and full peer rendering remain open.

Read poweredA and poweredB first; the grid result decides the next fix.

A no-wire generator test is first; current logs cannot separate registration from wiring.

Open-state support for server-named workshop refs is built and awaits flip validation.

Resource totals, happiness and assignment state are not synchronized yet.

Workshop NPC job scripts are not synchronized.

Aim, health and unconsciousness are built through actor roster paths; no game run yet.

Reuses furniture occupancy claims; suit-specific apply and ownership are not built.

The probe ships on by default so real quest churn can be measured.

QuestProgress, store, ordering and persistence are built; no game validation yet.

A query and debug panel can show stored party quest state.

No remote stage is applied yet; phase 2 requires per-quest opt-in.

Session-wide global sync is built with a deliberately empty allow list.

Config and data extraction exist; live probe data still needs to fill the list.

Dialogue remains private by default; no one is force-advanced.

Quest refs and quest-object inventory stacks are excluded from world sync paths.

The game opens the browser flow and receives the session back.

Kernel requires a browser captcha, so the in-game password forms were removed.

The site can rename through kernel and refreshes the local profile.

Search, request, accept, deny, cancel and unfriend are built.

Global, party and nearby channels. Confirmed with two players on 2026-08-07.

Confirmed in game on 2026-08-06: the marker sits on the spot you pointed at, carries who placed it and how far away it is, and shows on the Pip-Boy map.

The event stream makes a player online and closes cleanly when the client dies.

Shows server activity, but presence server ids remain client-reported.

Owners can claim and heartbeat servers; public listed servers appear on the site.

Owners can list, claim, rotate, move and remove their servers.

Staff can suspend and reinstate without leaking suspension state to owners.

Public announcements can be edited without a deploy and shown before sign-in.

Public social links are keyed, sanitized and shown on the site and in game.

Curated rows live in the database and can be edited from admin content.

Returns name, description, tags, slots, icon, ping and compatibility without joining.

Validated in game by owner report on 2026-08-03.

Icons are real PNG files and absolute paths; in-game browser display still needs final validation.

A full server refuses extra clients with a defined QUIC close code.

Servers sign a fresh query challenge with an Ed25519 key.

Local history uses proven server keys; the session-start identity fix just landed.

A save records the servers it has joined, and joining a different one asks first. Built, not yet run in game.

Backend and client sync exist; the session-start identity fix needs production proof.

Uses the larger of local and account totals; depends on proven key discovery.

Listed servers have public detail pages; private details stay owner-only.

Heartbeat samples keep 15-minute peaks for the server detail chart.

The registry returns an address only for joinable servers; private ids stay hidden.

Works when Fallout 4 is already running; launching the game from an invite is unsupported.

Discord request path is plumbed, but there is no production UI prompt yet.

A password opens an in-game admin menu whose commands come from the server, including teleports. Confirmed with two players on 2026-08-07. Admins by account are not built.

Friends, servers, account and controls live in one RmlUi panel.

Shows sign-in state, friends, requests and profile data in game.

Direct and registry server browsing is built; final in-game rendering pass is still open.

Every mod key is listed in one place and can be changed from the panel.

Bindings round-trip through the TOML client config with conflict reporting.

Escape capture hold is built to stop pause-menu bleed-through

One key hides this mod and the game HUD, validated in a running game.

Menus no longer stop the world for everybody, confirmed in game. A vanilla tutorial popup and some menus still stop it for the one player who has it open.

The main menu shows account state, announcements and social links.

Invite toasts keep their own RmlUi surface alive and draw above the panel.

RCSS alpha and font-weight traps are covered by project checks.

The plugin records crash RVAs for engine failures; coverage grows with live crashes.

fop-save-inspect can read the server save and confirmed live settlement records.

The dev script launches both game instances and seeds probe keys.

fop-query exercises the same direct query protocol as the browser.
