Disappearing Locations?

[korenv]

Hi,

I downloaded Barnacle Bay and Sunlit Tides, the latter of which was working properly.  One day I went to play the game and all the new towns I downloaded were no longer an option for me to choose but if I chose a family that I was previously playing that happened to be in that location (like Sunlit Tides) then I could do that.  I tried to reinstall the towns but that didn't work.  I also tried a fix on this site (can't remember which one) and that didn't seem to help either.  I know it's something simple so if anyone can help me on this it's much appreciated!
