Crashing to desktop, no error message

A couple times I’ve been playing the game just unexpectedly crashed to the desktop. It seemed that at the times of the crash I was moving around items in crates, furnaces, etc. One time after crashing I had immediately died, friends were around and no one had killed me. I was in a radiation zone with very low rad counts though so I do not believe it could have irradiated me to death. Don’t know if this is my computer’s issue or the game’s, but it hasn’t happened often enough to ruin the experience. I just wanted to bring this to attention.
