Hi all,
So I recently updated to Spine version 3.7.93 from what I believe was 3.6.37. Updating broke all the animations I already had in Unity and re-exporting alone didn't help. What I had to do was delete all the animation data and re-export each Spine file, and re-assign each SkeletonData asset to its corresponding game object. Once I do that and re-configure the animation mixers, it goes back to working fine.
The problem is then when I close Unity and re-open, the animations all break again and I have to do it all over again. The SkeletonData asset gives me this error:
The Atlas asset gives me this error:
And yes, I save the Scenes and Project in Unity before exiting and re-opening. It still reverts to this broken state.
