Additional information: link

RBET._previousRbBoostAndMarketingFee (#460) is set pre-construction with a non-constant function or state variable:
- _rbBoostAndMarketingFee
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.

Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#132-149):
- (success,returndata) = target.call{value: weiValue}(data) (#135)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
