Hi, not sure if this is a "bug", a known issue or a limitation of meshes.
If you create a mesh with an image then 'swap' it out with a larger image the scaling of the mesh is permanently changed. You can't return to the initial image.
Attached an image to help explain, hope it makes sense.
Thanks
This part of the documentation explains what is happening:
Meshes - Spine User Guide: Image resize
We should prompt so the user can make the decision for what happens when mesh images change size. I've added an issue to track that:
#205 Prompt for user decision when mesh images are resized
Thanks for the info.
case of RTFM :doh:
To be fair, that part of the manual is pretty new, previously it was undocumented. Also, Spine is making some assumptions for common use cases without asking you, so it's understandable the behavior looks confusing. 
We'll make it great again!
