Posted February 6, 2016 (edited) It appears that the tiles under a building on my property appear to generate side shaft warnings when I attempt to remine a mine tunnel perpendicular to them. I had a shaft that ran under a building but it collapsed. While mining it out I ran into this problem when I reached the first set of tiles directly under the house. I tried to go around but it appears to be the length of the structure. It looks like it is treating the building as a side shaft and not allowing another tunnel into it. Clearly it was not like that when I first made the original tunnel. Edited February 6, 2016 by tmouse Share this post Link to post Share on other sites
