So, I have had this a couple of times now, in 0.59 and in 0.60. Friends of mine have had this too and it doesn't happen every day, but it happened like 4 times to me. 3 times in 060.

What happens is that you're just playing and at some point everything seems to stop. Frozen image, no audio, no interaction possible. The only thing you can do is try to close the process down if you can find it because it stays behind the dayz window. A lot of people just power their computer down at this point.
