So I had discovered Spring and was checking out the faction HQ and then realised all the anti-slavers had started following me and my cursor was green when I moused over them. I ran down to the bottom of the mountain and they stuck with it but wouldn't help me fight a leviathan I found at the bottom and even the leviathan stomping on them did nothing to them and they didn't care. After reloading my last autosave I realised they started following after switching from my one member up in Spring to some nearby squadmates and then back again to load the area again. I tried another load and the same thing happened
Here is a bunch of them standing behind my skeleton, and Tinfist's goal is showing 'following'. I also couldn't initiate conversation with anyone in the entire faction HQ which I'm not sure is intentional or because I had a skeleton there or my relations with the UC was at positive (only 6) but it was something I noticed.
