So far this is exclusive for me in the Unity 6 open beta branch, this does not appear in the public build.

Since first booting up the Unity 6 branch my main avatar has been stuck on a year+ old version that I just can't get to update or reflect current version. I tried clearing cache (all of it), reinstalling vrchat, uploading a new version of the avatar (x2), switching worlds. Nothing breaks my avatar out of it.

I've tested a few avatars and my main avatar is the only one affected by this, the only thing I could point to as being unique or different about my main avatar is that it has over 300+ versions throughout the last couple years. I was able to skirt this issue by generating a new blueprint id and reuploading as a new avatar, that build of the avatar seems to be working and reflecting new uploaded changes. I'd hate to imagine who else is experiencing this unknowingly
