Reentrancy in HKUN.takeDividendBeforeSell(address) (#799-812):
External calls:
- swapTokensForETH(dividend,account) (#808)
- uniswapV2Router.swapExactTokensForTokensSupportingFeeOnTransferTokens(tokenAmount,1000,path,account,block.timestamp) (#875-881)
State variables written after the call(s):
- appendTotalDividend(msg.sender,claimedBUSD,false) (#810)

HKUN.handleFees(uint256,bool).sellWeight (#720) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

HKUN.addLiquidity() (#765-797) ignores return value by uniswapV2Router.addLiquidityETH{value: newBalance}(address(this),otherHalf,0,0,address(this),block.timestamp) (#789-796)
Ensure that all the return values of the function calls are used.

- burnFee = newBurnFee (#757)
- liquidityFee = newLiquidityFee (#758)
- marketingFee = newMarketingFee (#759)
- charityFee = newCharityFee (#760)

HKUN.takeDividend(bool) (#828-848) uses timestamp for comparisons
