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.
