Avatar Configuration hierarchy not saving

Hello,

I’m trying to import a model to use with VRChat. I mapped all the bones correctly except for the Spine transform not being a child of the Hips transform. I fix it, hit apply, everything looks good, but when I hit “done” my changes get reverted and now Spine is not a child of Hips again. What am I doing wrong? I’m using 5.6.3p1.

Same problem here, what im doing wrong?

I have the exact same problem, I just don’t understand.

Hello, I am having the same issue with Unity 2022.3.22f1 and above. Did you find any solution?
