TS4 Empty Town

If you read my Legacy you know that my town has slowly been losing townies.  I decided to look on manage worlds yesterday and discovered that they were all gone!  I found a bug thread called My sims disappeared here.  I couldn't find anything on the main forums.  Apparently someone has made a mod for it but I really don't want to use any mods yet.  Especially not when I'm on the 6th generation of my legacy family!  But anyway I wanted to post this picture here for anyone that doesn't believe me that my town is literally empty.
