Removing goals from the problem

[MannavaVivek]

Is there a way to remove a specific goal from a defined problem? I am currently using a system where I want to do something like
problem.remove_goal(previous_goal)
I know of the Replanner, but for some reason, the plans generated by the replanner with the same domain and problem pddl are much worse than the one generated by the Oneshot planner using the same fast-downward planner.

so I wanted to do it with multiple Oneshot planners instead but I couldnt seem to find a way to remove a goal as inbuilt method.
