Hi. We have faced texture distortion while using mesh and Constrains in latest versions of Spine.
In spine everything looks fine, but after exporting data in game, some meshes are cut, some are distorted and even individual bones with no mesh on it moved out of place. Some of them rendering on top of everything while they should be hidden underneath. Also we notice that after creating animation ant copying it to other place with same texture names but different content(like Boar lvl1 upgraded to lvl2), and editing mesh in that second animation - the result in game looks like in the picture below.
In both cases the result rendering is incorrect.

Steps 1:

1. create mesh
2. export is wrong

Steps 2:

1. create mesh
2. copy textures
3. edit textures
4. edit mesh
5. export is wrong

If you could fix this in some future versions - we would be thankful.
