Do these change the underlying base terrain? Or do they add a new tile on top of the base terrain (like flooring basically)?

@Cama That's a byproduct of them being craft able, technically it should happen with the rough walls too if they are destroyed. I'll dig and see if there is a way to disable that with the next update.

Hey, i'm not sure it's your mod but with the automatic rebuild in home area toggle on, smoothed stone walls blueprint are placed when you mine them

I always fix my map. This has saved me literally hundreds of trips to the dev menu. Been waiting for this, thank you!

This mod looks awesome, keep it up dude!
I love the way research is linked to general research milestones.
If I may suggest something to add it would be Overhead Mountains type of roof.
Also having a bunch of config options to turn off extra content or set work/resource cost per tile would be great. Looking forward to seeing future updates, I see great potential here.

I agree, big update coming soon. Things on my list is adding configs for work and some presets for those who want it harder, or plain cheating.

Finally... a terraforming mod with the new terrain types. Thank you so much. I do think the work amount should be a quite a bit higher though (given that there is no resource cost)
