This bug happened to me 3 times while playing on the OBJ server the 25th november 2014 (there was only one with more than 12 players running).
Description:
The whole game freezes. The only thing keeping on are the ambient sound loops. I could get back to the desktop so the Windows was fine. Could not however force the game to exit as it was blocking the whole screen (black game screen even on the desktop).
Reproduction steps:
No idea, seemed like the bug was happening without any reason (client-side). Mustang experienced the same bug.
Solving the problem:
Had to ctrl + alt + delete -> sign out to close DB. Then I can log in again in my session and it works. No pc reboot required.
