The problem was a short downtime of the database, the servers were not correctly loading. It can be solved by just restarting the server although I'm not sure if the /global servercontrol command is working correctly right now (and /shutdown is only working for me). I was checking a few servers after the problem and they were working fine, but it seems several servers were affected. I've restarted a few (Ventus and Sin City) and fixed the problem with incorrect staff lists. Please tell me if more servers are affected. I can add more developer gold time although that probably doesn't bring back the lost holiday time x-x
