So, even after rollling back to 1.0.2 and going past the balck box mission, I eneded up with a save which would not allow me to save - or, better- to manage my saves, even if I wasn't playing in ironman mode.
Whenever I was back at STIX the save button would just do nothing, and if I click the load game on the start screen the list shown would be empty.
I had to reinstall galaxy because it was messed up, and that changed some weird things, but can't really understand what's going on.
