Im sure this has already been shared, but cant be bothered to read all the threads.
the 'code' if i remember right was a quest bug. Basically after accepting a quest to kill some wolves, it didnt have a time limit and rewards showed it was just food. Was able to fight wolves, but unable to complete or abandon quest.
The last 3 was a combat bug. After initiating another quest to kill some rebels, when combat began game froze for a few seconds and combat wouldnt begin. They didnt attack, and I didnt have the option to.
(Another note: I have edited files, I simply increased the amount of starting points both PC and starting slave have, so I doubt it effected these two bugs).
