@Count Dooku, I've had many playthroughs and Abdirak has never been hostile, even when fighting all the goblins at once -- at most he's been a cowering yellow dot. I think that he might be tagged as an innocent bystander somewhere. Same with Gribbo, other than adopting Volo and staring wistfully into the distance she has never attacked my party.
With the new patch they are not marked as yellow. Both characters attacked my group at first before I did anything.
So I think this is a bug.
Another issue which I have in this temple is the destruction of the drums.
If I destroy one of them, Dror Rhagzlin started the attack. Even if nobody could see that I do this.
