VoiceRouter chose listeners by distance alone. A mod that puts separate maps in separate virtual worlds hid those players from each other, but a player in a dungeon standing on an overland player's coordinates could still hear them. The router now keeps each player's virtual world next to their position and skips a listener when MafiaNet::VirtualWorldsCanSee says no, the same gate replication streams behind. The tick feed moves into VoiceServer::SyncAvatars, which copies each avatar's world and drops cached recipient sets when one changes, so a map change cuts audio at once, not a refresh interval later. Server-only; nothing on the wire changes. The new router and avatar-feed tests fail with the gate removed.

Suggested reviewers: Merge Risk: 🔵 Low · up to Voice routing currently applies world changes before processing frames, but tests do not protect that ordering. The change is mergeable with this focused regression-test gap noted for follow-up. Security Architecture ReviewSecurity architecture risk: 🔵 Low · up to The new routing rule restricts voice to nearby players in mutually visible worlds, and a detected world change clears cached recipient lists. No new cross-world exposure was established. Voice behavior during a world change inside a packet-processing tick remains unverified end to end.

Voice frames are relayed inline from the packet pump, which ran before SyncAvatars. A world changed by scripts or PostUpdate was therefore first seen after one more tick of frames had routed on the old world and the old cached recipients. Syncing first closes that tick; the packets' own position updates are picked up next tick either way.

Problem
VoiceRouterpicks listeners by distance from the talker and nothing else. Replication already partitions players by MafiaNet virtual world, so a server that puts separate maps in separate worlds hides those players from each other. But separate maps have their own coordinate origins: a player in a dungeon can stand on the coordinates of a player on the overland map. They can't see each other, but they can still hear each other.Change
VoiceRouterkeeps each player'sMafiaNet::VirtualWorldIdnext to their position (SetPlayerVirtualWorld/GetPlayerVirtualWorld).ComputeRecipientsskips a listener unlessMafiaNet::VirtualWorldsCanSee(talker, listener)passes, the same test the interest grid andVirtualWorldReplica3use. That's one integer comparison per listener, and only when a recipient set is rebuilt.Instance::UpdateintoVoiceServer::SyncAvatars(const ReplicationManager &). It copies each avatar's position and virtual world. When any player's world changes, it drops every cached recipient set, so a map change cuts audio at once instead of up tokRecipientRefreshMslater.VIRTUAL_WORLD_DEFAULT, matchingNetworkEntity. A player inVIRTUAL_WORLD_GLOBALhears and is heard in every world, within range.Server-only. Nothing on the wire or in the scripting layer changes, so this should be a PATCH.
Testing
voice_router: 5 new cases. A listener 1 unit away in another world is skipped in both directions, while one in the same world is still heard. The global world reaches every world. Range still applies inside a shared world. A player with no world set is in the default world. A reused GUID does not inherit a removed player's world.voice_positions: the server-side test now drives the realVoiceServer::SyncAvatarsinstead of a copy of the tick loop. It also has a new case where two avatars stand side by side in different worlds, can't hear each other, and hear each other again once they share a world.FrameworkTests: 466/466 on this branch. HogwartsMP builds and its tests pass against the change.Summary by CodeRabbit
