To people with crash errors, the same thing happened a while back. Yes your rank is gone for now, and your cash is screwed up. Go to your achivements, and rank, and friends, then take a screenshot that includes your rank as viewed by Kong, and as viewed by the game, and send an bug report explaining the error and with the screenshot, and they'll fix your account when the server is fixed.
