Hello 2q2bforgotten, I went ahead and made the adjustments for you. You can download them here. You did a very nice job merging your maps together. I hope your little people love their new home.

I did notice in your list above that your kitchenUpgrade.png file has an extra png in the name. Make sure that you edit the name of the file so that it says exactly kitchenUpgrade.png otherwise the game won't "see" it and neither will you when you're playing.
