So, problem in Grymforge: after triggering the fight with Nere (I had some of the duegar and the gnomes on my side), one of my characters got disarmed. When she picked up her weapons after the fight, all of the friendly duegar and the gnomes we had just saved all went hostile. Had to put them all down, although I managed to merely subdue the ones I was in melee with with non-lethal damage. I mean, it's pretty ridiculous that they would turn on me for scavenging after we defeat Nere together, but I get that they are greedy. But no way should they go hostile because I pick up my own weapon that got knocked out of my hand while I was saving them!!!
