Glitches.
Theories:
The house gets split apart, with different sections going into the medium as players join.
The house goes to one planet, but is then teleported again to a second planet, leaving a player without a dwelling spire.
Two players share a planet.
One player is unable to join the game (Think the kids parents being brought in).
One player is brought in along with the house, the other is left in a house shaped hole with a meteor coming at them.
Romans 8:31 What, then, shall we say in response to this? If God is for us, who can be against us?
1 Corinthians 13:1-3 If I speak in the tongues of men or of angels, but do not have love, I am only a resounding gong or a clanging cymbal. If I have the gift of prophecy and can fathom all mysteries and all knowledge, and if I have a faith that can move mountains, but do not have love, I am nothing. If I give all I possess to the poor and give over my body to hardship that I may boast, but do not have love, I gain nothing.
