For those receiving the “…Refuses to follow you” message I would ask if you have any mods that modify followers?
When updating my mods with pets I learned there is a new field on the Profession Template table there is a new field that defines whether the pet is a ‘warrior’ a ‘demon follower’ or an ‘undead follower’ basically.
If that field is not populated players will receive the “…refuses to follow you.” for those pets.
I suspect if you have a mod that is altering thralls, it may have touched the Profession Template table and impacted the base game companions.
Try removing your thrall/pet mod and see if the behavior clears.
I’m getting the same issue. No mods for pet/thralls installed, just the Dude’s mods. I tried removing all mods but the issue persists. Restarting the server, Steam, and the game client had no affect.
for me when i removed Dudes_Creative_Constructions made by TheDude from the load order everything works again, the others 2 mods dont gave me any issues yet
