I've recently got an issue with SourceBans version 2.0.0-dev that it remove random admin server groups, I assume it has to do with recent changes in steam id universes calulcations.
Or I might be wrong, I don't see any certain errors or crashes in server or web logs.
It seems that the groups are lost quite randomly when leaving a server.
Any help would be greatly appreciated.
Here I would keep a list of my plugins, if I had any
