Seems the vault did took away the old unobtanium pack without replacing it. What will I spend my unobtanium on now?
You can save your Mana Jewels for the next Elite Pack that will be in game when the HOU set arrives
I hace two packs pending to claim, not 800 unobtainium units, two packs, will they update to the next Elite packs or should I just claim them now?
I would wait. Are there any cards in the set?
The one time I was credited a replacement pack for a dupe pull, since it took them long enough to credit it to me, the one I pulled from had expired and the next pack was up. In my case, I could only pull from the pack it was purchased from. Mine was tied to the set it was purchased from, leading me to believe there is a strong chance yours will be as well. There is no harm in waiting, though. If it is tied to the pack you spent the jewels on, you will still get what you purchased.
