Pinned Scroll Animation Loop Issues

Hello, relatively new to readymade. I have a small icon pinned in the corner of my page that rotates with the scroll animation. However about 25% of the way down it stops. No matter what I change any of the parameters to it stops at the same point. I also have the speed at the minimum 0.1x. Any suggestions/workarounds to get it to loop?

you could add another animation step and repeat the animation, or let it rotate in the negative direction.
Or if this isnĀ“t working add a step with speed 999 to go back to the start and then another step like the first. I would guess, that the user will not really notice the possible fast rotation step.
