Tool Animation doesn't look the same in game than in studio?

I'm animating a lasso tool and it looks aright in studio, but when it's played it starts to spin crazy.

Any ideas are appreciated.

Animations in the roblox plugin plays kindda different of course. Recently i have noticed that the easing directions are all inverted when played. So try inverting all of your easing directions, even if they are all linear, cause that seems to change something too. Tell me if it works.

If just this dont work, use "add keyframe here" in the spots that you see that the lasso is spinning wrong so that movement wont be ignored.
