Problem with Animation Editor?

Currently I'm trying to make a character animation that looks like a dragon. But for some odd reason whenever I try to animate it in the Editor, it's frozen. I have tried UNanchoring the HumanoidRootPart But it sends the HumanoidRootPart Flying in a different direction every time I open the editor with some other part.

Could it be because I'm Animating a Rig that's more then 5 parts Or I need to update the Editor itself?

This is the character Model that I am Animating.

Any assistance that is constructive would be welcome.

PS I apologize if this doesn't qualify as "Scripting" But the assistance on the forums was... nonconstructive.
