Game crashes when I try to play specific lots in Del Sol Valley other than mine

thesoulfulsoul​  When you say it didn't work, do you mean that the new save is affected, or the old save is still affected after you've removed your Mods folder?  If the latter, please try a different, previously-unplayed, default sim or household in your main save, as I mentioned before.  It's possible the mods broke the sim you can't play with.
