Note: Probably affects 1.16 pre-release 3, haven't tested it in that version yet though

When attempting to sleep in a bed that is not your current respawn point during the night but failing (for example, the bed is too far away, occupied, or there are hostile mobs nearby) does not reset your spawn point, despite it working during the daytime under the exact same conditions.

Edit: Might set respawn point but not show the respawn point set message, haven't done much testing so I don't really know
