One nitpicky correction:
1) Notate the number of beds and baths of the corrupted lot.
2) Move/Evict the household from the corrupted lot. (You can move them back in later).
3)Save the lot to your "My Library" under Open Gallery (F4) Bulldoze the original lot.
4)Place the saved lot from your My Library onto the corrupted lot currently in-game. (So, basically, you are replacing the corrupted lot with itself which will trigger EA code to reset the lot attributes)
5)Make sure you go to the i info menu and update the correct number of beds and baths of the lot before saving the newly placed lot. (This is VERY VERY important because it triggers a reset of the lots attributes)
