Sure, there's always going to be somebody who falls through the cracks, but if you've done a soft reset even right before the event started, it isn't unreasonable to expect that you can unlock Pamu and date her within the two days that the event's been going so far plus one for her entire 24 hour period of eligibility. The girls beyond Pamu, not so much.

And if you did a reset after the event started, that's your own fault.
