I have about 75 hours logged on DayZ so far, haven't had any issues. I was playing yesterday and the game suddenly crashed back to Windows (no warning/error messages). So, I logged back in and my server list was blank (Every tab). Tried periodically throughout the day with the same result.
I tried verifying my game cache through Steam, and ensured my DayZ server filter is set to 'Default'. Connectivity seems fine.
At this point I am not sure what is preventing me from pulling the list of servers and playing.
Any assistance would be appreciated, thanks.
