I had that bug too today for the first time but Im not using the mod to fix it. It fixes one thing and breaks groups in camp. I don't want people following me around in camp. The modder said he won't fix it. I think its more like an side effect of the fix and he can't fix it. So its fixing a bug and causing another.
Because unlinking the group is so hard, isn't it? The author finds it funny to have the team following, big deal. I'd rather have to unlink the party at camp, than having to move one character at a time, all the time, because their AI is broken.
