The problem occured when I logged to server that was restarted few minutes before. I was unable to use any item then. I've noticed that new players were not able to loginto the server (did show up on list without any connection details (ping, speed etc), and after few moments they were disconnected. My coleege disconnected from the server and tried to reconnect and he apeared on server without any gear. When he restarted the game client the gear came back again but he didn't log into any server so I'm unable to give You any additional details about outcome.
