Hi Z,
I'm running across either an error or a lag. Earlier today, I cashed in 15K points (earned, not bought, if that matters) to upgrade from having choices up to a Spad to including a Nieuport. The points were taken out of my balance, and for that game session, I flew the Nieuport. Now, reentering the game, I see my low balance, but the Nieuport is priced at 15K and is not "in my hangar." If I back up to the Spad, that's available in my hangar.
Android 2.3.4, HTC G2 phone, everything else working great in the game.
Thanks,
Manfred
