Posted September 22, 2022 Need more information about cave ins not happening to houses From: https://www.wurmpedia.com/index.php/House Underground Housing It is possible to build houses in caves. You can build any type of wall underground, however you cannot build roofs in cave dwellings. In order to do this you would need to activate a hammer, mallet, or trowel and right-click a flat, reinforced cave floor tile. Houses can only be built touching a cave wall if and when all the tiles are on deed and they do not have an adjacent perimeter tile. If any of the adjacent tiles are perimeter tiles the perimeter tile must be mined out. Alternatively, houses in caves cannot be built touching a cave wall if they are off deed. If you attempt to plan a house that is outside the previously stated parameters you will get the following message: You cannot build here, there must be a gap around the building.
