I love that you included your save, and nobody even bothered to load it up and realize that the ecstasy enlargers aren't working right AT ALL. /s
Fortunately I did :3
After some investigation, I discovered the code to shrink them was arranged in such a way that it could never trigger. What's more, I identified a weakness in the way it processed size loss that would make it shrink much slower than intended when resting for long periods. The way it was coded, once the status hit 0, it would shrink 1 size level, then set the status to tic five minutes more and repeat... but it could only trigger once per time passage event. Waiting five hours or waiting five minutes would result in an identical amount of shrinking.
It should now scale with the length of time passage when triggering. I was able to rest and drop your breastRatingMod value on your primary row from 55 to 37, consistent with the "Ecstasy Enlargers..." status effect indicating that it was responsible for 18 points of breastRatingMod.
