I don't think is a bug, I probably missed some option or something but my player character seems to be walking floating like 1 foot over the ground but the character controller is perfectly placed
I had this problem at one point. However I fixed it by changing the coordinates under 'Transform' in the inspector of the prefab. There's also a place on ground script in Ork that could help.
I fixed it by reducing to the absolute minimum the skin width in the character controller.
