Minidump information:


On second run, it didn’t crashed. This engine crash seems to be rare?

Stop using DirectX 8.

Crash actually triggered whenever game was paused (in SP) or by going to main menu while in MP.
Interesting, it doesn’t crash in DX9 mode… Can you explain it a bit (due my curiousity)?
