My Custom Rig is not Rotating

Hello everyone!

I’m making a simulator that need to use rigs that aren’t Roblox’s default. So, I’m having trouble with some of these rigs because they’re not rotating. I know their rig is fine, because I can animate it (and the animations work) and Humanoid.AutoRotate is set to true, so I don’t know what is wrong.

edit: I already tried a lot of things, such as setting all the parts (or just the HumanoidRootPart) to massless (I know, it seems like useless but I really don’t have idea), redoing the rig, play the place as published, but nothing worked yet)

(obs: sorry if I put that in the wrong category, i really don’t know where to put it)
