Owlbear Cub Makes Camp Hostile

[Kyir]

At some point several hours ago, I cast Animal Friendship on the owlbear cub (I think I must have mistaken it for speaking to animals or something similar). When the buff wears off, most of the camp immediately becomes hostile. I've seen a couple posts in various places about this, but no solution.

Does anyone have an idea about fixing this? It seems unintended.
