2) Creatures in combat on slopes should work better. If there are still issues I would need an exact location to check as it's dependent on the terrain.
Another issue I found is that while mounted you can summon as many pets as you want without the other pets going back.
Random Slope I checked and still having issues. Here you can see both the pet (Shadowbear) and the target (Mutant Squirrel) are not attacking each other at all.
