Something went wrong with a former commando. After each actions, the game generated some kind of error, created a log file and then needed me to press enter.
I cleared the monsters who were threatening me and then found that there is a former commando who is unable to shoot. Putting him out of his misery ended the errors.
Here's my error.log

Let me know if you need more details; I have screenshots of pretty much the whole thing, how it looked, what solved it etc.
