Lost booster pack.
I bought a Zendikar booster pack. I tried to open it and the game said "Unable to open booster pack", then it went to contacting server, and when the main screen loaded up maybe half a minute later, the pack is gone.
I also lost a booster this way. Wish there was a fix.
I had the same problem, 2 of my 50 boosters did not open and were subtracted from the amount.
abri unos sobres y se colgaba en esperando servidor, y despues no tenia las cartas y no me contaba la para sumar los comodines. perdi sobres y puntos para nuevos comodines
