Variable 'VAULTS.swapBack(uint256).success (VaultS.sol#643)' in VAULTS.swapBack(uint256) (VaultS.sol#624-654) potentially used before declaration: (success) = address(address(_distributor)).call{value: address(this).balance}() (VaultS.sol#649)

VAULTS._tokenTransfer(address,address,uint256,bool) (VaultS.sol#523-572) performs a multiplication on the result of a division:
-tFee = tAmount.mul(fee).div(feeDenominator) (VaultS.sol#528)
-burnAmount = tFee.mul(_burnPercentage).div(100) (VaultS.sol#550)
Consider ordering multiplication before division.
