Are you talking about things like aggression and confidence values? If so, those are covered by the Actors.AIData tag.
No, the AI package lists attached to an NPC record. There are I believe two tags relating to the package lists (I'm at work, cannot look things up right now), I'm just wondering whether these packages will take ONLY the AI package list data, allowing any other edits to the same NPC record from earlier in the load order to override when bashing (even when the earlier loaded mods have no tags relating to NPCs).
This'll get locked soon, I hope queries from old threads get carried into and answered in the new one
