UANG.addLiquidity(uint256,uint256) (#1317-1331) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,deadWallet,block.timestamp) (#1323-1330)
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.

UANG.totalFees (#952) is set pre-construction with a non-constant function or state variable:
- liquidityFee.add(charityFee).add(marketing1Fee).add(marketing2Fee).add(burnFee)
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.
