Turns out the wife was not a duplicate, but the same person. They gained weight at the same time in both areas. Anyway, I got the one in the new area moved back into the care home and then got her back into the new area and that fixed it. Also thanks for adding additional text for the end scene as well to help clear that up.
I was also thinking the same thing when it came to the advancement/promotion idea. Feels like the best way to unlock more stuff in the new area, with the interactive scenes being the bonus for players and maybe some other stuff inbetween and after you reach the max.
Anyways, thanks again for all these awesome updates! Can't wait to see how much this game grows over time! ;-)
