Same ragdoll script won't work in new places

[XKlsGX (tibem)]

I have a Ragdoll script that I’ve been using for some months. In games that I made in january it worked with NPCs and Players. I’ve been rewritting the game code in a new place. But the only thing that isn’t working is the ragdoll script. When I copy and paste the “older” npcs in it, It works but not with “newer” ones neither players (Still works in the old game tho). I have the same Avatar and World settings. I don’t know what to do…

Solved! I had this “AvatarJointUpgrade” on… I didn’t even knew what was that until I went reading updates here in the forum… But done! Wish this helps for anyone reading
This kept me days stuck lol

you should have added “nvm”
because I love when OP solves his problem with this word.
