So me and a mate both live on student res and recently walked down memory lane and play some bots.
We found this and thought perfect but when in a lobby together issues arose.

The way it goes is, I can see him on the screen but he is never moving; when he hosts I can see the monster take dmg from him and die but his model remains still, whilst if I host he just stays still and no dmg is done by him. At the same time on his screen he sees us both move however he can never draw agro and my attacks can never kill of an enemy, they either sit on 1% until he finishes them off or they get stuck in a constant state of tripping over. Often when I attack it trips bots over for him and when that happens they are immune to him until I die, then he may hit them from hull health in one shot.
