Yeah, the first event chest worked fine for me two weeks ago, but on the second one for a while there I was getting the pic of the event girl with 'NAME' and 'RANK' placeholders where her actual name and rank should've been, and I was still getting the pic on the faction screen long after I opened the chest. But I'm at 1/10 with her after getting the second chest, so it at least seems that I've received the card for the second chest.

I wish they'd kept the old chests in there and not given us this lame event girl. If we grind for-freaking-ever to max her out, one card per week (assuming you get the winning faction every time), what is her last rank ability even supposed to do? You can't restore 10 HP to a unit because after you lose the 10th HP the unit is dead.
