HonorLand.withdrawExternalToken(address) (#572-577) ignores return value by IERC20(_tokenAddress).transfer(withdrawAddress,amount) (#575)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Contract ownership is not renounced (belongs to a wallet)
Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains
HonorLand._initSupply (#456) should be constant
Add the constant attributes to state variables that never change.
Additional information: link
renounceOwnership() should be declared external:
- Ownable.renounceOwnership() (#398-400)
transferOwnership(address) should be declared external:
- Ownable.transferOwnership(address) (#406-409)
Use the external attribute for functions never called from the contract.
