I cannot delete this mod, because it doesn't bring kovarex back

Done. Update to 1.0.1 and the option will be available.

While you're here, could you tell me what you didn't like about this mod?

Thanks! I do like this mod actually. It's a very interesting idea to replace kovarex process with multi-stage processing, that gives you even more energy. I want to try Plutonium Energy mod, and I assume, these two are not really compatible. Maybe you should unite these two mods, btw. It would be great!

And also, I guess this should be in map mod settings not in general
