I thought these things were only supposed to attack a structure if you agro them? I just had a group start beating on the walls on the opposite side of where I was at. Was painting the stuff I had just built earlier so I wasn't making enough noise to attract them. I just heard them suddenly start beating on the walls in a line and not all bunched up. I went over and shot the first one and got the sneak damage bonus on it. Of course the others reacted to that and I didn't get any more sneak damage. Killed them no problem, but was surprised they were attacking the walls in the first place. I have had this issue with closed doors too before and no one could explain it then.
Did they Wandering Horde AI get changed so they target player built structures in their path?
