POPTIGER.swapBack() (#418-434) performs a multiplication on the result of a division:
-liquidityTokens = contractBalance * (buyFee.liquidity + sellFee.liquidity) / (buyFee.marketing + buyFee.liquidity + sellFee.marketing + sellFee.liquidity) (#420)
-ethForLiquidity = ethBalance.mul(liquidityTokens).div(totalTokensToSwap) (#430)
Consider ordering multiplication before division.

POPTIGER._transfer(address,address,uint256) (#362-415) uses timestamp for comparisons
Dangerous comparisons:

Pragma version^0.8.13 (#11) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.13 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
