Game "freezes"

[Farzeer]

I was able to play for a bit. Did like 5-10 missions just fine, no problems at all. Now, when i start a mission, i can play through most of it, and then the game just freezes (Zeds, civilians, helicopter, nothing moves at all.) I can relocate all the stuff, and hear the audio of them relocating but nothing happens. I can also move the camera, hear the music etc.

So basically the game is still running fine but all the units are frozen. Anyone else have this kind of issue?
