I installed 1.06 earlier today, and started a new game.  I got a notification a few minutes ago (after I restarted the game after one of the frequent crashes) that a new update was available.  I think it was 1.06.018 to 1.06.019 or something like that.
 
Anyways, I installed it, started the game, and tried to load the save I was playing just 3 minutes ago, and was told that it's incompatible with the current game version.
 
Ummmm.... wtf?  If I'd known that this minor update would invalidate my saves, I wouldn't have installed it.  At least not until I finished my current game.
 
Can I assume this is a bug?  Is it something you might fix in the next minor update?
