When a player sleeps in a bed, everything seems normal to them, however to other players the persons feet are hanging completely off the end of the bed, as shown in the pictures below.

How to reproduce:
1. Have a friend join your world, set the time to night, and have them sleep in the bed.
2. observe as they are hanging of the end of the bed with not a care in the world

Note: This appears to only happen in some directions? Try reproducing in all cardinal directions.
