So I bought on the App Store, which I now regret, but here we are. When I launch the game, a small window pops up which offers me access to civ packs, DLCs, informs me of challenges, etc. That window is how I purchased the previous civ packs and DLCs. When I go to buy the newest one (Maya and Gran Columbia), the "buy" button seems to do nothing. Is there a fix for this or a workaround whereby I could purchase the new civ pack another way?
