Extreme corset will eventually trip the implant check
Check for implants (assayWidgets.tw) will trip if waist < -95, current extreme corset events will eventually bring waist below that every time. Assuming this isn't the desired outcome, potential fixes are to stop waist shrinkage at waist < -90, or both stop shrinkage at waist <= -95 and have implant check trip at -100 (to not trip in cases such as -94-5=-99). Or maybe add a revert to -95 in the case that the event sends it below -95.
Now that I think about it, that last approach sounds best. I've already pushed the simpler solution to my personal tweaks, I'll push the latter solution as soon as I'm done writing it.
