Yes, I had strange behaviors happening, like some NPCs being out there at night and in the rain doing their daily stuff where it obviously makes no sense. A good exemple I have in mind is witnessing Mila Valentia at 2PM dancing all alone next her mother's vending place. I've also had a guard being unhappy with me and asking me not to drop weapon right after simply using the grinding stone. Lastly, while having a rescue mission in my journal, I saw the NPC I was supposed to rescue, respawning at his house and leaving on foot to join the bandit camp where he was supposed to be captive. I think I've had this one happen a long time ago, before I even started using STEP to mod my game. I can't be sure it's AI Overhaul acting up or simply bad luck on my end with scripts breaking up for whatever reason but I never had that happen with ICAIO. Anyway, hope all that feedback helps!
