I have a very strange situation.
One of my SkeletonGraphics needs Multiple CanvasRenderers set to true and generates 4 additional renderers. They show with a plus cause they are not yet added to its prefab.
The prefab itself does not even generate as many, only one. When I try to add one of the generated ones of the instance it generates another 4. I can only delete the latest ones as the others get regenerated after deletion to keep the original 4.
I think this all happened because in the Prefab I could disable Multiple CanvasRenderers without any complications and Trim Renderers without a problem, I was left with one.
Overriding the prefab in the project folder helped solving the discrepancy.
So why is the behavior of how many renderers are required different in scene and prefab mode?
