I am missing the trophy that says Clean house inside and out. I can't find anything wrong with my house either inside or out. Can anyone point me in the right direction? Thanks

Almost certainly you've got a weed growing somewhere that hasn't been spotted.

You must complete both the Spring Cleaning and Order in the Yard trophies to be awarded A Gleaming Estate. Depending upon which of those two prerequisite trophies you still need, you should do as Arnie suggested and carefully look for a missed weed, or (if you still need Spring Cleaning) you will need to search the inside of the house for a missed sock, wrapper, or cobweb.

Try cleaning the cobwebs. I had this problem and could not find anything I had missed, but when I cleaned the cobwebs, I got the trophy.

Maybe you missed a dirty spot somewhere? Try to add the mod to highlight the collectibles - it makes it easier to see where all the weeds and spots and wrappers are.

This seeing stars one, from Lyssaria is a great one!
