CryptoClansToken.swapAndCharge(uint256,uint8) (#946-963) performs a multiplication on the result of a division:
-liquidBalance = tokenBalance.mul(_liquiditySellFee).div(_liquiditySellFee + _sellBNBFee).div(2) (#951)
-bnbForLiquid = newBalance.mul(liquidBalance).div(tokenBalance) (#957)
Consider ordering multiplication before division.
