Please make it work as so bitter won't come back after running. Also if resources are comming back (not sure, haven't checked), please make they don't. Could you fix this or put an option to select this?

The goal is to reset undeveloped areas back to their original unexplored state. It is outside the scope of this mod to modify map generation settings.
It would be quite a bit of work to remember which chunks had previously been generated and preempt the regeneration of those chunks to selectively disable resource and biter generation. I believe there are other mods that globally disable biter or resource generation. Maybe one of those should work with you manually enabling and disabling it?
