I've had a few combat crashed, but this one was a little different. I exited combat fine; my sovereign gained a level and I put it into essence, took it out, then put it back. Clicked on done and the game crashed to desktop. Links below. It also generated an impulse reactor log file at the same time - do you want that one as well?
