So, you break all prior saves for the final version of this game, instead of making the final fully compatible and THEN moving on to the new tech for the sequel? Thanks for the big "F.U.!" to all of us! In spite of all the previous difficulties caused by your constantly changing the game's underpinnings and/or content I would've recommended this to people until this version. Now I have to put you on the list of developers to avoid.
There is a reason "saves" exist, understand? Doing what you just did is equivalent to making us stand in line all day at the DMV only to be told, right before we get up to the counter, that we have to go to the back of the line because the forms we filled out when we got there have been superseded by new ones during our wait. Of course, the main difference is that we actually NEED the DMV...
