Animations Become Weird During Run-Time

Hello There! I was recently learning Blender Animations and I have a…weird problem.

I did an Animation in Blender, sent it off to Roblox, and in the Default Animation Editor, it looked fine

But for some reason when I played the same animation in-game, things changed.

Anyone know why this is happening?

EDIT: Found that the HumanoidRootPart was facing the wrong way for some reason, so the joint overwrote the animation in runtime.
