I am playing on Valhalla map on a dedicated private server. Only mods running right now are stacker plus and corrected structures. I have been trying to build with pillars in the area of 52,58 on the map. Its and extremely flat area and shouldn't have any issues placing pillars there but when go to place them I can place a few but when i start going up hill (which is barely an incline) it will say can not place structure here. The pillar is by no means too low in the ground and I cant snap it to a higher point because the ground isn't high enough. It was doing this before the corrected structures mod was added. Please help. Server is on survival servers.com
