Recently today, an avatar creator had deleted all their content, and my favorites list is bugged. Currently, there isn’t any workarounds unless I can properly unfavorite the avatar. I didn’t have 16/16, but my last four avatars are listed twice (And an extra random favorited avatar if I ‘unfavorite’ the deleted slot).
Can there be an update later to automatically unfavorite deleted (“Avatar Not Avaliable”, with default VRChat logo) avatars?
I cleared my cache, reset local user data, unfavoriting the avatar… nothing worked.
Edit: Now able to unfavorite and refavorite (Well, to unfavorite any avatars favorited after the bug, that updates), but the deleted avatar slot hasn’t updated.
Edit 2: My favorites list for adding new friends doesn’t work. Might be affecting the favoriting system entirely. Possibly affected the functionality of favoriting worlds.
Edit 3: I heard that the VRChat Cloud updates somewhat biweekly to clean/refresh deleted avatar ID and such. Hopefully it refreshes my list soon. If the VRC team is watching, broken favoriting lists (that result from unavailable/blank favorite spots) have been an issue since 2017. If you do get time to fix it, it will most likely benefit everyone on VRChat.
Final edit: Favorites list updated, as I can finally resume normal favoriting of avatars/users. As I did absolutely nothing to fix the issue myself, it might be either my account cloud was refreshed, or something that I don’t know about.
