So, I've started the attack on Bishop Alexandar and his cronies at the end of Fort Joy, and I've managed to get the Seekers to join in (by teleporting him back to near their camp) ... We're basically chatting and chilling and picking off Magisters as they wearily make their way up the stairs.

Until one of the Seekers, evidently bored with the ease with which we are winning, attacks and kills Simone.

No, no one was charmed (although Sebille does have the Captain's Armour, but since the Seekers are our allies, that shouldn't be an issue). They made a few other questionable plays as well, mooching around, doing nothing, and casting heals on characters at full health.

Did my cheesy exploit break the AI?
