Being able to log back in a game.

A /invite friend can be a thing.
You can only invite a person once and they have to stay only on your island for a minute until you can start interacting with things around you. (so people can't start abusing things)

Not to sound rude or anything, but as annoying as this is, it's not really a pain in the ass to just join another game, is it?
