Ass shrink potion shrinks breasts

Huge breasts just instantly turning into a flat chest. My character was overjoyed (grin)

Digging into the code, using the potion just calls player's us() method which is where the problem is. So this likely affects other ways to reduce ass size, such as crimson manuals.

I can't quite understand what the us() method does but it calls both reverseUSRoute (which tests butt size and sets breast size) and reverseBSroute (which tests breast size and sets butt size).
