[EDIT: ISSUE RESOLVED BY SECOND PATCH - NO LONGER AN ISSUE] I loaded the game and my saves were gone after downloading a Steam patch just now.  I found the forums a bit hard to navigate and found no solution (nor warning it might happen) there.  Also, no entry of what the patch was was found despite a link to see patch notes in game.  My expectaitosn were not really met, but I get its early access etc I was just surprised...
