I logged in my account today and my CP was at zero. I know I have over 300,000 CP. I'm not sure what happened and I haven't made any purches. It leads me to believe that someone got into my account. I know it's just a game, but it kinda ticks my off. Thank you.
You do not appear to ever have had 300,000 CPs, and there are no records of you having donated $300 which would be the only way for you to acquire those CPs. Perhaps you mistook your credits for your CPs at some point. Your credits, however, are still intact.
