I'm just trying to figure out why my packages are not working on my summoned mobs. Do Packages just not work on summoned creatures or Non humans like Skeletons?
I am pretty sure they have their packages overridden by some default "minion" package of sorts, which basically tells them to follow the player around at all times and attack anything the player attacks or is attacking the player. It is likely unchangeable.
You could circumvent this by using a script to create the actor instead of the default summon magic effect archetype.
