I had this issue a few times - didn't end well for me as I had to redo my household (twice) - so hopefully we can avoid that situation here. This won't be fun to clean up unfortunately
You have an outdated mod somewhere screwing things up. Remove the less popular mods first with scripts. Fire up game, see if that fixes your prob. If not, you're going to have to pull all mods that use scripts, then fire up your game and see if that works. If that doesn't work, start a new household and see if new household looks okay. If so, then the household might be lost but the problem would have been removed (as in, the bad mod would have been removed from the game).
Then you'll have to slowly add mods back into your game - start with Wicked Whims, Nisa Perversions, MC, Sacrifical's Mods. Fire that up. Make sure you're good to go. If so, slowly add your best mods (the ones you really want) after you've verified that they're updated. Add like a few at a time since if there's something off, you'll be able to remember which ones you put in there and go through the process of elimination.
Important - just because you found one "bad mod", doesn't mean that's all of em. Best to slowly go through everything bit by bit until you're sure there are no "bad mods". UI Cheats as one person suggested is a good culprit but it may not be the only thing that is causing your game to act wonky.
Important 2 - If you reload and it appears to be okay - start playing for a bit before fully committing to loading everything back in again. Sometimes the problem will pop back up a few minutes in (I can attest to that >.< ).
Tip - Make a folder on desktop. Transfer all your mods from your Sims Folder to the desktop folder. Your first bunch of mods that should be okay will likely be updated Wicked Whims, Clothing (you dont have to move those), Animation (dont have to move those), Poses (dont have to move), Nisa Perversions, MC and Sacrificial's Mods. Once you're set there - drag from one folder to the other.
Hope that helps :/
