On the Dwarf Fortress Wiki page for Aquifers says to do the following to remove aquifers:
"Find the files in Dwarf Fortress/raw/objects (new world) or Dwarf Fortress/data/save/regionNN/raw/objects (already saved world). Open the three files with a text editor (e.g. Notepad). (inorganic_stone_layer.txt, inorganic_stone_mineral.txt, and inorganic_stone_soil.txt) Use Edit->Replace, and replace [AQUIFER] with (AQUIFER). (Use 'Replace All'). To restore the tags later, do the same in reverse. (Replacing (AQUIFER) with [AQUIFER])."
I did all of this for both the new world and already saved world methods, and checked to make sure that [AQUIFER] no longer exists in any of these files, and the aquifer is still there. Does anyone know if this is the right way to remove aquifers by modding?
