    You can't downgrade the web version.

    Is there a way to fix this issue? I've had the same issue and me and my team are kinda in a hurry to finish a modpack. We wanted to redo one animation but now it stopped exporting properly. If I need to fix it in the JSON code that's no problem, someone just needs to tell me where.

    Thanks for the help!

    Also how long will it roughly take you to update? I'm not in a hurry after I know how to fix it in the code but still.
