I just hat to find and remove am 88GB sized ouput_log.txt because it filled up my C: drive. Apparently there is no mechanism to restrict its size. As it resides in a hidden folder, some people may find it difficult to find it.
I still have the file if you want it, but attaching 88GB here seems a bit much. Should compress well, though.
No idea, I just let the game run. It did crash overnight though.
