Pet Followers Wont Work.

Hello. I am haven trouble with the followers. The do spawn correctly. but the partials will give off lua errors. But when i rejoin the server the one i already have equipped will work correctly. But when i try another one it happens again… is there a reason for this? or did i install it incorrectly on the server? lol
