I started playing DayZ again a few weeks ago, after a break of approximately 8 months (although I played a few times now and then). Recently, the game started crashing after ca. 5-20 minutes of playing. It occurs on stable servers on the latest version (0.61), on both the normal DayZ and DayZ x64.
It always shows the message "Instruction at 0x00530613 referenced memory at 0x00000008. The process "read" could not be found in the storage." (literally translated from German, here's a screenshot: http://puu.sh/tOegR/755ea78b51.png)
The bug randomly occurs when I interact with the inventory, like moving, swapping or combining random items. It happens more frequently in bigger cities/villages. I have 16GB RAM and already checked it with MemTest and everything was fine. Google couldn't help me find a proper solution either.
