Adds the ability to dig the underground, move item and fluids between surfaces and blow away pollution.
Mods introducing new content into the game.
Map generation and terrain modification.
New Ores and resources as well as machines.
Subsurface is forcibly rewriting the map gen while it's in the modlist, I have a islands gen setup and it reverts it to default upon exiting the starting chunks
the map gen settings for the subsuface is probably accidentally being applied to the nauvis surface level
Same issue was on GitHub (https://github.com/NathaU/factorio-subsurface/issues/6) it is fixed for the next release
