I used the drag and drop method and it worked fine.

Worked for me as well.  Thank you!

For some odd reason mine keep ending up in my family's inventory.  I stick them in the graveyard, build a nice little plot for them, save town, and the next time I play they are gone.  I think my sick and twisted family enjoys digging up dead bodies and carrying their dead relatives around.

It is probably a clothing problem.  I continue to experience it on and off with new clothing I download.

Try this...
1)  Delete the outfit your sim changes into when they bathe/shower.  While this can be a hassle (trying to find the file is a royal pain) it seems to be the only thing that works.
2)  Do the steps described earlier in this thread. 
     - Edit your sim in CAS using the awesome mod, indie-stone mod, or super computer
     - Change your sim from male to female or visa versa
     - Accept and go back into the game
     - Go back in CAS again and change the sim back to it's original gender and accept
     - Try showering/bathing again and see if they are now nude. 

If they change into a different outfit it means you still have some borked clothing.  You will need to delete each outfit they wear when nude until this stops happening.

It's a hassle, but it fixed it for me.

I have them in my damn art gallery too.

Ok that is too funny!  Thanks for the laugh!!!

You can now add me to the list of those receiving that damn Error 12 upon save.  My game was fine (with the exception of a bad CC item which has been removed) and never crashed once.  I've never had any problems at all.  Now all of a sudden it absolutely will not let me save.  I just keep receiving error 12 over and over.  I'm on Windows XP, and I have the dreaded patch. 


I believe this to be the case as well.  My saved game file is now huge.  I'm going to remove some things and try the compressor on all of my downloads.  Maybe that will help.  If I can get the save to work again, I'll also turn on the auto-save on the Awesome Mod.

EA needs to fix this damn game.  This is ridiculously frustrating.

Thank you, Nauthiz.  That did fix the problem.

I should note that I never did have that sexysims hack.  It took me hours to figure out exactly what was causing the nudity problem on my end.  (I have way too much crap downloaded for this game.)  It turned out not to be a hack at all, but some donation clothes from Peggy.   Once I isolated them and removed them and then changed the sim from female to male and then back again all was finally fixed.

I'm not all that surprised by the culprit.  I'm just glad I didn't pay for those files.   

It has been removed.  Unfortunately I'm having the same problem as Nauthiz.  All existing female sims continue to change into clothing rather than get naked when showering.  It is always the same outfit so I'm assuming the game has this saved somewhere and is pulling it up whenever they are to be nude.  I've deleted the cache files as well. 

I am hoping there is a way to "fix" the existing sims.  Is there a way to clear out the old data? 

All of my females upon reaching adulthood shower in some random item of clothing.  NEVER naked.  It is driving me absolutely apeshit.  Does anyone have any idea how to fix this?
