I have a very similar issue, seems that I’m reaching a limit that some of my AI will stop moving, if I get close to the AI, it will attack normally, but doesn’t move, if I delete the actor that isn’t moving and replace with the same actor, it will work fine, but some other AI will be stopped in the level.
Really looks like a limit, I’m using detour crowd ai controller, tryed to add this lines below to the DefaultEngine.ini but still does’nt work.
