Something like that happened to me with the trooper key. Only 4 battles counter and 450 sands used and all troopers played during the same time. I was running US Calvary Ed to get the major.

The thing that bugs me about this game is all the new tons and we never use them unless we're in gauntlet. No new worlds to conquer. Only the usual ten million runs in the same existing world. There's no real need for new tons that'll never get used. The thing that becomes sadder is the new tons are really not new. They're only cheap copies of pre-existing characters. Why??? Is there nothing new? There's so much Maiden lore to still build on, but nothing but bugs and rehashed bench warmers.
