Maybe the creator of the game was checking out the settings, and made the game NBC, but when NBC got in, he changed it back...? Not sure really. It's happened to my friend before, but he made it NBC for a minute.
I've been a BC'er many of time's. I had TBC,BC. I don't think I should have to pay $200+ for permanate BC. It's called " Not having everything you want ".
