I have been contacted that a player can't play Graveyard Shift, it crashes. I asked him to send the log files. output_log error.log He uses Windows 8.1. The GraveyardShift.exe caused an Integer Divide by Zero (0xc0000094) looked like important to me. There is no divide by zero in the beginning scene of the game, though. Game works fine for all other thousands of players. What might be the problem? We use Marmoset Skyshop, by the way.
