warmanw Thank you for sending the Spine project that reproduces the issue! I've confirmed that the issue can be reproduced using your Spine project, but I'm still investigating how to reproduce it when creating one from scratch.
At least one thing I can say is that linked meshes seem to have a bug where they enter a strange state when moved to a different skeleton:
What's strange is that in this example, even though flower_2 is linked to flower_1, flower_1's icon has become a regular mesh attachment. Additionally, in the viewport, linked meshes should display vertices as double circles, but when this bug occurs, the vertices appear identical to those of a standard mesh attachment.
Therefore, I believe it's certain that moving linked meshes between skeletons is causing some issue. However, regarding the distortion, it doesn't always occur solely under the condition of moving linked meshes between skeletons and importing the animation. I'm currently investigating additional conditions.
