I tried to reproduce from the 'before' saves, and was unable to do so. Probably because I didn't perform the same actions the second time around.
I've attached both sets of save files anyway, but good luck. Sorry I don't have anything better for you.
No problem, if they're that intermittent and such it's probably not hurting much. Most AI thread logic is just "loop everything I have, see if I want it to do something different, and then do it again", so if it messes up on one go-through it'll get it next time. All the errors I saw in your log were the sort that would just interrupt it on that cycle and it'd retry a brief moment later.
Still want to fix them, but I don't think it's causing any major malfunctions.
