RobustSwap.balanceWithdrawToken(IBEP20,address,uint256) (#1941-1951) ignores return value by _tokenAddress.transfer(_recipient,balanceToken) (#1950)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

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.

Combination 2: Unchecked transfer + 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.

RobustSwap.getTotalLiquidityAmount(uint256) (#1583-1601) performs a multiplication on the result of a division:
-amountRBSPerBNB = runningBalanceRBS.div(quoteOutputBNB) (#1590)
-totalLiquidityAmount = amountRBSPerBNB.mul(minAutoTriggerAmount()) (#1593)
Consider ordering multiplication before division.
