Bug #427

Session becomes unjoinable after network error and restoration

Status:	New
Priority:	Critical
Added by:	_kadonk on March 15, '25

Due date:
Reported for:	S5.09

Steps to Reproduce

1. Open a game with at least 2 people (you included).
2. Start a mission.
3. Connection/Wi-Fi error on either end, doesn't matter (can be done intentionally by turning off your router).
4. Be auto-kicked from the session as non-host and connection fixes itself.
5. Try to rejoin.
6. Game either gives notification 'This session is no longer available' or does nothing at all.
7. Bug can be fixed after mission is over/failed if the host clicks on 'disband team' (seeing as it can't be done during a mission, it isn't really a solution to the bug because you can't save your mission progress).

Explanation

If the host or teammate encounters a brief internet error (e.g. network failing) and connection is later restored, the entire session will be completely un-rejoinable by no-one.

Session will not be visible in the server list even if it is public.

Steamoverlay will send out bugged invites to friends making them unable to join the session. Clicking on "join game" doesn't work as well.

Session is practically perma-solo until host "Disbands team"
