I noticed a lot of the NPCs that aren't companions (Scratch/Owlbear Cub/Cat) don't walk around and even a few of the NPCs that you can invite to camp in Act 3 don't even spawn. The little girl who comes with her cat Grub has now stopped showing up entirely after I saw her the first time I went to camp after inviting her. Seemed that after I closed and reopened the game the next day she stopped appearing. Most of the NPCs that move around and feel alive in Act 1 and 2 camps just....stand there and don't move at all. They appear in the same places in each camp and do nothing.
