No argument there; I'm very curious as to the metric used for this. It could be that the medals are being given out in waves based on some criteria such as time played. I have no idea, but I would like to know and if it is some arbitrary thing where those who didn't get the medals aren't going to get them I'm going to be upset as well (even though I did get them).
Something time-based where everyone will eventually get it: no problem.
Something only given out to certain accounts and everyone else is SOL: big problem.
It's also entirely possible that the medals shouldn't have been given out at all; if that's the case I wouldn't be outraged if the girl I got was removed so long as I get back the resources I already dumped into her. If it was a bug, then I hope the devs employ a unilateral fix: give the medals to everyone else or remove the medals/girls from those who got them (and return invested resources!)
