The AI seems to have problems with certain actions and gets stuck. With EHRGEIZ, a bot gets out and then continually cant decide whether to go somewhere or get back in the vehicle. This mostly happens with a Demon.

With Citadel, the bots seem to have problems with jump pads, as in this video : https://www.youtube.com/watch?v=P75CP37_--s&feature=youtu.be - This problem also seemed to introduce graphical errors too.

Twin peaks also has this problem, its only the demon. i haven't seen anything about jump pads, but i've seen AI repeatedly trying to jump on top of surfaces too high to jump on to in artifact XL
