My packs disappear when their price changes.

I logged on and I wanted to play one of my packs, it costs $7.99. I had a lot of packs and none of them showed up other than the ones I got for free. My $7.99 pack is now on the Marketplace for 4.99. This has happened to me before but with only two of my packs (They were free at the time I got them and the price went up on the Marketplace). I spent a ton of my money on these packs, I had between 20 and 30, most being around 5 to 8, USD. I'm pretty sure this is a bug that happens when prices change since that is the only time it happens to me.
