Where did my Hanweir Garrison go?

Oberoni

I just collected enough of the once-a-day rewards to get a Fat Pack. I opened up several packs and got the Garrison (the 5/6 one). However, I looked through my cards, annnnnnd...it's not there. I still have the Hanweir Battlements, but I've had that for a while. Anyone else experience something like this?

Did you check on SoI rare cards on red?
I first assume that both card is same color (they're not).

Good idea, but nothing there. This is really odd.
