It needs to be fixed on an architectural level:
maybe each Score should have an unitialized entity count which counts as a higher score level (harder than hard).
Planner must managed that unitialized entity count itself, it shouldn't force the users to deal with that.

> DefaultSolver.runSolverPhases() will go through each phase, and will revert
> the changes if they're not better. Or, more exactly, here are lines 191-193:
>             if (it.hasNext()) {
>                 // solverScope.setWorkingSolutionFromBestSolution();
>             }
> Now, if this involved setting the planning variables for the first time,
> those will be reverted.
