Lobby ID: #607151
Date & Time: 11 Jan 19:45 UTC
Not sure if this is a known issue, but I couldn't find a bug report related to it, so basically (using a lobby this just happened in as an example):
1. Lobby starts
2. It turns out to be a flobby, so the leader ends the Serveme reservation, however the leader does not close the lobby itself in TF2C
3. After 2 minutes, a few people automatically get reported for being disconnected (and have their reliability lowered), followed by the lobby closing automatically (EXCESSIVE_SUBS)
Maybe this could be solved by checking if too many people left at the same time before lowering reliability?
