It's really not broken. You evidently made some choices they didn't like, or chose to attack them when an option to do so popped up. This goes a long way towards showing that there's more than an illusion of choice at work here.
it only happened when fast traveling back to camp no dialogue are ways to prevent it from happening even the dog we had in the party i even had max reputation with shadowheart and she just attacked when we went back for long rest
This is the 2nd time that ive seen this topic come up in what...3 weeks?
If its a bug its not one that many are running into id say. Filing a bug report might do more good here then posting about it on the forums.
i have posted bug reports many are running into this even one of the hotfixes said they fixed it but it is still happening so i posted this here to get the most coverage for it to get fixed its been the only problem i had in the game so far
