MetaFashion.manualBurnLiquidityPairTokens(uint256) (#1057-1078) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp > lastManualLpBurnTime + manualBurnFrequency,Must wait for cooldown to finish) (#1058)
Avoid relying on block.timestamp.

MetaFashion._previousTaxFee (#636) is set pre-construction with a non-constant function or state variable:
- _taxFee
MetaFashion._previousLiquidityFee (#639) is set pre-construction with a non-constant function or state variable:
- _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.

Pragma version0.8.9 (#6) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.9 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.
