Players can go invisible when moving their play space. This bug isn't only in the beta and has been around for a while. But it felt good to place it here.
  1. Look away from the other player.
  2. Have the other player move their play space far up into the air.
  3. have them reset their play space down to the ground again.
  4. look at where they stood before. They aren't standing there.
  5. look up to where they moved to and they will reappear.

The player popping in is visible for all other people before they pop in for me when I look up.
