Quick answer: Construct 3 Photon multiplayer rooms persisting after host disconnects? Photon's host migration sometimes fails - configure auto-cleanup on the room or migrate via fallback host.
Host crashes. Room stays in the lobby list; players can't join because the host doesn't exist.
Set EmptyRoomTtl
Photon room property. After 10 seconds with no players, room auto-closes.
Use Master Client migration
Photon auto-elects a new master when current disconnects. Verify the migration logic in your project.
Manual host election
Players can vote a new host. Code path; works as fallback for the auto-migration.
“Networked rooms need lifetime management. The host isn't immortal.”
Test host crash scenarios deliberately. Kill the host process; verify the room and clients recover. The scenario must work.
