BullishAF.addLiquidity(uint256,uint256) (#713-726) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#718-725)
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.

BullishAF.swapAndLiquify(uint256) (#674-691) performs a multiplication on the result of a division:
-tokensForLP = tAmount.div(_totalTaxIfBuying).mul(_liquidityFee).div(2) (#676)
Consider ordering multiplication before division.

Ensure that all the return values of the function calls are used.
