EDIT: I found out I had self-interactions off. So that made contacts and receivers not work. Turning it On fixed it.
This canny can be disregarded now.
What I am showing you in this Canny post did work ingame a week ago and before.
I am not sure what day exactly it stopped working, but yesterday (10/21/2023) it stopped working on all my previous uploads (one is from April 2023, id is avtr_8e0cd56e-c24f-49c0-8cf2-884d586490e3).
I also tried to reupload one of the older uploads and test it in Unity and both ingame.
Such attempt is attached in this video: https://youtu.be/vM2pP04twoo
Avatar ID : avtr_70111b38-0ade-4068-aec1-480b2b7c04f5
The summarisation of the information in the video is, that contacts and receivers in some of my avatars stopped working after upload.
In Unity everything works, and it worked before ingame.
Also a bone seems to be scaled up on it's own for some reason.
I am attaching a screenshot of the hierarchy of this avatar + settings of the contacts and receivers.
This also happens on the current Open Beta.
