Marshmallow PB v1.2 and v1.3 (https://booth.pm/ja/items/4511536), a gimmick with constraints is broken in open beta.
Right breast behavior is completely broken and unstable in OpenBeta 1484 but was working in Live 1472.
The test avatar is uploaded with live version of VRCSDK (3.6.1) but I found this bug with avatar uploded with much older (2019) SDK.
Here's the avatar can reproduce this behavior: avtr_f0539ea8-6902-43e0-81e7-60bd39f178c7
Wearing the avatar or seeing user wears the avatar will see weird right breast behavior.
We can see relatively stable behavior in rare case but moving a little or touching breast would show this problem.
The preset for Marshmallow PB is Very soft. If you're trying to reproduce with your avatar, it might be required to change preset to Very soft.
