There's a mod to fix CAS aging

Just came back to report that I opened my throw away save and took my sim into cas for several minute. She went in with 15 days to age up and came out with 15 days to age up. So then I exited to the main menu, and started a new save spent several minutes in CAS editing that sim and when I came out she had 22 days to age up on a normal life span, which I believe is standard, and no green in the progress bar. So by my testing the mod seems to fix the problem and so I am going to start slowly adding back my cc into the throw away save, and test it all and put my long time saves back into the game.
