It sounds like it is indeed something I can help with. I'm here if you need help fixing your bug.

I hope this doesn't turn into a casinobit style mess for investors.

If the bankroll is higher than actual coins held, investors will have presumably been able to withdraw more than their fair share of the real coins, leaving the house somewhat insolvent. That's what happened at casinobit, and it didn't end well.

Well done for shutting down the site while you investigate. That's something casinobit never did.
