Was playing solo to level 7, then turned on online mode, played with someone for half hour or so, but had to go, so I saved and exited. Then when I got back and put it to solo mode everything disappeared. I only see the land, elevators and water. I had a present that brought in a human, which worked. The human is there, but that's it. I went up 4-5 levels and down a few and nothing. The ship pieces show up as well, but I have no way to get more presents or anything. I can just keep continuing up the levels till I win I guess. Not much fun that way.
