Just a summary of issues that I've run into:

 

1. Druid class AI - the first one. Even if I don't check off "Use Per-Rest Abilities" my druid will *still* use per-rest spells.

 

2. Ranger Pet auto-attack AI: does not work at all. I got it to work once, but ever since then the ranger pet just acts as if there was no AI involved (I am trying the "Aggressive" script).

 

3. Paladin targetting AI (the class script that focuses on damage): it may happen to other AIs, but my Paladin has gone *running* off to attack no one with Flames of Devotion. It must be some enemy selection glitch, because these series of screenshots shows my paladin running all the way to the *exact* center of the map before using Flames of Devotion on nothing: 

 

4. Ranger class AI - the first one. I literally never see my ranger use Marked Prey or Wounding Shot. One time I noticed the ability icon flicker in the ranger's above-npc tooltip before the ranger settled on ranged attacks again.

 

 

Here's a drop box link for the ranger AI bugs:

Just enter combat to the right and note that neither pet nor ranger will do anything interesting. Ranger will auto-attack, but that's it.
