We have multiple images with same name for one mesh. When we reload another image which is same name, same size as before, the mesh has been changed. Look the follow attachment, left is right, right is wrong 
Meshes works incorrectly

I have seen this happen and closing and re-opening spine fixed it. Does that work in your case?

Thanks for your suggestion, but it doesn't work. I don't know why it happened. When it happens, I create a new project and rework step by step, it's fine, good. Then, I continue to do other work. When I back to check that meshes, sometimes it's fine, most of the time it's wrong, even other meshes also be wrong.
I may not rework again and again, so, I don't know what I can do
