Yes, indeed, that is really evil

:-D, but since they speak about a "rain check", you should allow the possibility for the double date with the cops to happen anyway in a future update - maybe you could even just reuse the same images and code, since the ones that did not do it immediately, did not see it yet.
By the way, for the cheaters in you
the variable that is used to decide whether she goes out with the two cops or stay at home (meaning, possibility with William and then going to walk the dog), is called ch3_double_cop_date, if you set it to true, you go with the cops, if not, you get the other possibility, so you just one save for both paths.
