Happens in vanilla with summon monster or animate dead - when I load a game with any summoned monsters, a number of them will stop following me or attack anything and just be idle. If I save and reload, even more of them will become idle. Anyone else getting this?
I was just going through your post and came to know about the query. The thing that you have mentioned is almost the same that I am also facing and I don’t know if it is any kind of bug or not or the game requires an update or not.
