Spring Arm weird rotation

I’m making a camera system where the spring arm is always oriented towards the enemy. It works fine but I wanted to add some interpolation so that switching between enemies is smoother. I am running into a weird problem where the Rotation Yaw of the spring arm is changing suddenly for just 2-5 ticks and then goes back to normal. Unfortunately those few ticks are enough to screw up the calculations inside RInterp. Here are some screenshots to help illustrate the issue.

This is the initial situation. You can see that the world rotation of the Spring Arm is around 22.

The second screenshot demonstrates a situation where I just pressed W. As you can see the Yaw goes above 30 and then goes back to 22. This causes issues when using RInterp.

Finally, here’s the BP where I do those calculations. For now I’m not using the result from RInterp since it causes the Spring Arm to shake a lot for a few seconds before stabilizing.

For now I have solved my problem by checking “Enable Camera Rotation Log”. However I would still like to know what causes those little changes to the components rotation.

I have the exact same problem, waiting for answers.
