yeah ok i see that they are upgradeable now....not sure if i never noticed before of thought that it was stupid that the upgrade costs in game money and has a chance to fail....cost me like 65k and half an hour of my own time to upgrade all my gems to lvl 5 and i only got like 3-4 lvl 5 gems out of it....
looks like the update today 08JUN is going to add back in the ability to create(host) multiplayer matches again......course i just get an error when trying to download it......ayecarumba!
