Game crashes when loading certain houses

So i'm a huge CC lover, although bumpy along the way I can usually play my game with lots of CC and its fine

but recently I made a couple of cool homes using cc and I can access them through build mode but whenever I move a family in and try to load the game, it always crashes and takes me back to the map with an error code. I'm guessing this problem is probably CC related however this doesn't happen with all my households, I have plenty more that load fine with CC in them. 

Any idea why I can't get my two recent builds to load? 
And is there any suggestions I can try without deleting all my CC because I'm an addict and can't play without

Thank you!

You need to check item per item to see which one(s) need to be updated to be compatible (or which one/ones is/are broken).

You can MOVE your CC somewhere else to test it out and find the culprit.
