The issue is not caused by a logicall loop, as is explained in the fourth video.
After reviewing I found out it’s actually a Blender bug. It’s the transformation constraint which is causing this.
It’s a hardly noticable artifact and it depends on the amount of tread sections used whether it becomes noticable.
This means you can’t use this tread system (with a transformation constraint) when going beyond 90 degrees, with other words keep the animation or drive distance short.
Maybe there’s an alternate solution?
