Test.addLiquidity(uint256,uint256) (#1351-1365) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: bnbAmount}(address(this),tokenAmount,0,0,marketingWallet,block.timestamp) (#1357-1364)
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.

Test._transfer(address,address,uint256) (#1224-1332) performs a multiplication on the result of a division:
-fees = fees.div(100).mul(sellFeeIncreaseFactor) (#1308)
Consider ordering multiplication before division.

Test.totalFees (#893) 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.
