So, I have a save game where I'm trying to get all the achievements, and the last two i have is to get the wanderer probes, and to activate all of the gateway engines. I'm on vesania with just about all of the engines finished, and everytime I either save the game by getting into a seat or my rocket the game boots me to the xbox menu. My thought was that I have done so much that the game is having trouble handling the amount I have done to each planet, but that's just my theory. I hope it can get fixed soon.
