I read something about that, and it was one of the things I initially checked. I just double checked for sure, and all players have a home planet, so that can't be it.
Well you only get a game over if the game can't find a homeworld for you, so I can almost promise you somehow it is the issue. For example, you may have accidentally added more players than you intended to use, in this case you must delete them as you get randomly assigned a player on the map by default.
