This is how I found that works. If you play single player when you create the game you are NewPlayer0. If you are playing a LAN game with a friend he will be NewPlayer1, etc. If you go to Edit, Players in Galaxy Forge and set the TeamIndex to 0 instead of -1 for NewPlayer0's home world you will spawn at that planet everytime. I think that you are always NewPlayer0 so you have to make the home world you want to spawn at the home world for NewPlayer0. The same goes for NewPlayer1 if you are playing with 2 people.- J
