Rotation problem with root motion enabled

I’ve been looking for a system to ride a horse, I know mine is not the best (if you could help me with that too would be nice) but the main problem is that when a montage animation that has EnableRootMotion is playing, the character rotates way faster and smoother and it’s related to framerate, you can see it here:

The problem goes away if EnableRootMotion on the animation.

Horse is a skeletalmesh inside the character BP, I rotate the character not the horse and it’s a multiplayer game with dedicated server; here’s the code:

The code has been simplified on MoveRight, it has a lot of stuff but when the player is using the horse that’s the only part that is used.

RootMotionMode in AnimBP does nothing to solve the problem.
