gusty crater
Me, Trip and M!ld did a test, It seems with the newest build people who are already in the session when you join appear as floating heads, but people who join after you are fine and look normal.
The newest person to join while looking fine on your end will see you as a floating head.
so the last player to join sees everyone as a floating head. The first person to join sees everyone fine. people who join in-between see a mixture.
tested multiple times with all of us and was consistent behaviour.

also tested in the persistent build world and in a new session. behaved the same way.

*Okay. So with the little testing guys. If you already have a build up in thr Neighborhood session and you try moving any of the current parts around after you relog, it will more than likely reset to its original position. It seems to be a permission issue. But if you spawn a new object and replace it, it seems to stay persistent even if you relog.
