This bug never occured to me again after release of v1.04. That solved it at least for me.

Exactly the same error for me. It always happens after approximately 1 hour of gameplay. After a restart, the game crashes after only 5-15 minutes. I never experienced crashes to desktop prior, even during the alpha.
Attached my crashdump and dxdiag.

Please let me emphasize that i never experienced this crashes before the hotfix. Whatever the hotfix fixed, it is probably the cause for all the crashes reported herein.
