Sims revert to default underwear

[lht1982]

For some reason, my sims always revert back to the default underwear.  I'll click on the sim, change the underwear from the default to something different, and then the sim will wear that new underwear.  For a while.  It seems like sometimes after the sim leaves the lot and returns, or sometimes after I've saved, exited the game, and started to play again later on, the sims has reverted to wearing the default, white underwear again.  Anyone else have this problem and know how to solve it?

It's possible for the underwear data to reset, but I have no reliable knowledge on when and how it occurs. Any attempts to reproduce it fail and each person reporting it has it occur in different circumstances that are not reliable and don't happen from game to game. As of right now, there is no fix for it.

Every time I set a custom set of underwear for my sim and then I exit the game and come back, my sim's underwear rests to the default. I have had this issue for a long time, and have been unable to fix it. I have tried running the game in administrator mode and still it happens. Very repeatable
