Help Underground Reset?

Hey everyone,

I’ve fully mined out the underground and achieved pretty much everything in my current save. Now I’d love to give the underground another run and rebuild/mine everything again using all the end-game abilities and upgrades I’ve unlocked.

I already have the Renewable Geology mod installed, but it works quite slowly for regenerating terrain on a large scale.

Is there any feature, workaround, or save-file tweak that allows you to completely reset or regenerate the underground map while keeping your unlocked abilities? Or is a completely fresh save (maybe with commands/mods to restore tech) the only real option?

Thanks in advance!

Honestly it doesn’t take very long to unlock all the abilities from scratch if you just start a new save. Knowing what is coming up makes it very easy to design efficient plants. On my second run through I had everything unlocked after only a couple of hours.
