Unable to play with my sim(s)/ or household

I recently downloaded mods & cc to my pc, and they all worked perfectly fine the other day. However today when i tried to play, my household that I created was all deleted! I double checked my mod folder to ensure everything was installed n no lags, so I'm not sure what am i doing wrong. Secondly, whenever I made a new house/hold (since everything was erased even after i saved it) I still was sent to the world map and unable to access any households. Anyone know how to fix this?
