NFTMania.clearStuckBalance() (#337-340) sends eth to arbitrary user
Dangerous calls:
- (sent) = address(owner).call{value: (address(this).balance)}() (#338)
NFTMania.swapBack() (#385-429) sends eth to arbitrary user
Dangerous calls:
- (tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#412)
- (tmpSuccess,None) = address(devFeeReceiver).call{gas: 30000,value: amountBNBDev}() (#413)
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.

NFTMania.swapBack().tmpSuccess (#412) is written in both
(tmpSuccess) = address(marketingFeeReceiver).call{gas: 30000,value: amountBNBMarketing}() (#412)

Fix or remove the writes.

NFTMania.totalFee (#210) is set pre-construction with a non-constant function or state variable:
- marketingFee + liquidityFee + devFee
NFTMania.swapThreshold (#234) is set pre-construction with a non-constant function or state variable:
- _totalSupply / 500
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.
