The problem is the rotation. Even though I have it set to rotate one time, 360 degrees from where it’s at, it seems like it just rotates like crazy and ends up with some random rotation.
Before, I had a delay followed by a set rotation to 0,0,0 at the end of my timeline update output, in order to combat the weird leftover rotation, and that actually fixed all the problems I was having, but left me with a new one. It would do it every tick, leaving it to look like it was snapping back to zero rotation every other frame or so.
