I'm getting a "user_already_exists" error from /user/save_user_settings no matter what settings I try to change. The JWT is valid, and this is happening on multiple instances the same (programming.dev, lemm.ee, etc.) Anyone have any ideas why I'd be getting this? Here's my payload:

{
  show_bot_accounts: true,
  auth: token
}

Edit: This issue describes a bug where this happens when the avatar field is not included. Just tested it and that's the same problem I'm running into. I fixed it temporarily by passing the current avatar url.
