I'm going to keep addding to the top thread with those oath breaking instances you've experienced directly, so that we can get an idea of the moon logic behind this ancient oathbreaking thing.
@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.
