Random game crashes since Patch

[outbreak]

Well as the title states in just one night I had 3 game crashes compared to the 0 before the patch, I have had the game nearly a month and no problems.

The problem ususally arises when I take off in a plane, It either crashes when i get on the runway or just after takeoff and well once during mid-flight. If you need anymore info let me know.

BTW dont know if it matters here were the planes i was flying when it happened:

1st - 190-A8
2nd - P39Q
3rd - P40E


All happened @ A78 on Grinder

[outbreak]

Ok its Monday Staff is in, Any ideas?

btw:
