Fixed a major multiplayer bug for players joining a saved game while the host is still loading in. Was causing many different bugs.
Fixed joining players sometimes being unable to pick up buckets after the deposit machine sent them out, and items floating or sitting in the wrong place after being thrown or carried by drones or robots.
Fixed a host who went back to the menu and hosted again not showing up in friends' Join lists until they restarted the game.
Items saved below the world are now put back somewhere safe, instead of falling over and over.
Players are less likely to be disconnected during a long load or hitch.
