So I've worked on a very big animation for awhile and somewhere along the line the animation in the Skeleton disappeared. I have all the dope sheet there with all the animation and I can get to it if I toggle between ANIMATION and SETUP, but the animation section in the tree shows no drop down of animations within it anymore. If I create a new animation, it appears as the only animation and I can longer work on this one I've been making. I started in 3.8.11 and updated recently to the 8.5.*s.
Please advise, I'm at risk of losing hours of work because I can't copy the animation over to repair it. Sadly I'm unable to recreate this, but I've had similar things happen when updating from past versions.
I've uploaded the json and there is animation data in there.
