Hello kxs, unfortunately since I'm new I don't have access to mail, but I've notified the rest of the team (:
I'm sorry you're experiencing problems, I'll try to kidnap Moo so Nate will be obliged to look into these bugs.
About the third bug, in the studio I work we've had the same issue, here's a roundabout until it's fixed:
- downgrade spine to a version that opens the file
- export a json with nonessential data checked
- update spine to the desired version
- import the json to the new project
