CIRA.addLiquidity(uint256,uint256) (#1420-1434) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,marketingWallet,block.timestamp) (#1426-1433)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

MarketingDistributor.swapAndLiquify() (#888-908) ignores return value by CIRAToken.approve(address(uniswapV2Router),tokenAmount) (#896)
CIRA.claim() (#1275-1278) ignores return value by busdDividendTracker.processAccount(address(msg.sender),false) (#1276)
CIRA._transfer(address,address,uint256) (#1290-1401) ignores return value by busdDividendTracker.process(gas) (#1391-1396)

CIRA._transfer(address,address,uint256) (#1290-1401) performs a multiplication on the result of a division:
-fees = fees.div(100).mul(sellFeeIncreaseFactor) (#1374)

CIRA.totalFees (#958) is set pre-construction with a non-constant function or state variable:
- busdDividendRewardsFee.add(marketingFee).add(liquidityFee)
Remove any initialization of state variables via non-constant state variables or function calls. If variables must be set upon contract deployment, locate initialization in the constructor instead.
