Same happens with 1.01 saves in 1.01 game. No crossversions.
Update to 1.02 did not change anything. Still main save file and both autosave files won't load.
And there are other threads, where customers reported the same problem days ago.
STARDOCK, THIS IS A MAJOR BUG - THE GAME IS USELESS BECAUSE OF THIS PROBLEM! NOBODY WANT'S TO PLAY A GAME WHERE A SAVE CAN'T BE LOADED AFTER 12+ HOURS OF GAMEPLAY! AND YOU DON'T EVEN RESPOND TO ALL THOSE PEOPLE?
