I've been working on a new movement system for both third person and first person and I keep running into this problem where if the player (in this case a cylinder) rotates beyond 90 degrees it starts rotating fast like crazy.

I'm not sure if this is a bug but I need some help fixing.

Here in the video you can see in the top left, when the rotation goes beyond 90 it'll start glitching out:

Greetings,

When it comes to applying rotation to a collision object, it can pose some difficulties.
Therefore, we recommend using the "Rotate Towards" command instead.

To illustrate this, please refer to the following example:
