I wasn't thinking, and I've updated my Spine Editor to the latest version, for a while now. Well, now our game wont import the skeleton data or json correctly. The formatting from a v3.7.xx to v3.8.xx seems completely different in the 3.8 versions. The runtime (which is 3.7 I believe) wont open them.
Is our only option to update unity with the latest version of the runtime? I don't really have a way to open all these new animations in Spine, since they are v3.8.xx.
