Baldur's Gate : The Sword Coast Chronicles : NWN2 Persistent World

I've noticed that very rarely my summon will turn and take a few swings at me lol... Thankfully my buffs keep them from doing any real harm, and they seem to go back to being my loyal servant after a few swings... But this seems like a bug! Even still, I've been using it as a little inside joke about how summons not appreciating being summoned in the middle of dinner, or their favorite tv show.

Can we assume you had a protection spell running?

Edit: Some summons really dont like being bound to service.
Did you use AoE spells, or what was the situation when it happened?

It needs a few seconds for the summon to be put under the player's control technically wise.

Probably AoE. I've been using AoE spells since I tend to summon a fire elemental and he is already immune to my particular choice of said spells. I think I did the 9th level meteor spell earlier and he turned on me for a second lol.
