Hi there. I am attempting to create my own mass entity processor, but unfortunately it crashes with this error:

LowLevelFatalError [File:D:\build++UE5\Sync\Engine\Plugins\Runtime\MassEntity\Source\MassEntity\Public\MassProcessor.h] [Line: 116] Pure virtual not implemented (UMassProcessor::ConfigureQueries)

I would love to have this be fixed.

Pure virtual functions are functions that must be implemented in your class. In this case, you must implement UMassProcessor::ConfigureQueries in order to compile.

Additive.
If you don’t clear the "Super::ConfigureQueries(); " An error will be returned.

hi there,
I’m currently working on the same MASS simple movement demo. And it successfully build and run. However, my processor seem would never execute. I also inserted breakpoint inside the execution func with no running into.
Does anyone meet the same problem? I‘m happy to hear any possible solution.
