Hi,
This affects at least the latest version of the Spine editor. I'm not sure if this is exactly a bug, but if you're generating a trace and you set the following:
SET 1
Detail: 99
Concavity: 100
Refinement: 100
vs.
SET 2
Detail: 100
Concavity: 100
Refinement: 100
SET 1 generates lets say 19 vertices. But SET 2 suddenly will be more than double that of 19. I checked the mesh, and there are double vertices that's on top of each other.
