i didnt restart steam after the download.
it was the first time i started the game after the update to stress test #15
i havent experienced any further crashes after this one
i played for about 20 minutes

steps before the crash:

• spawned in on the test server "DayZ DE 0-1 (Stress test)"
• pulled out IZH-Rifle via hotbar while standing
• chambered a bullet while walking and started running while loading the bullet in
• walked into some trees
• crash
• i was 41 seconds on the server until i crashed
