I can't seem to build anything on these 2 particular tiles, including objects, utility and foundation. In utility view, I noticed that one of the tiles is solid black, while another has a black outline. I have circled them in the 2nd image.

Is this a bug? Or am I missing something?

  • Can you upload your savefile somewhere so I could look at it in-game? – Sumurai8 May 23 '16 at 11:51

Seems like a bug, as usually the only parts of the map you cannot build on is the road, the very edge of the map and water.

Save your game and open the save file in a text editor. You can locate the map tile in the file using the X,Y coordinates and see what it says is there.

For example here are the first few tiles in one of my save games:

BEGIN Cells      
    BEGIN "0 0"        Mat PavingStone  Con 0.00000  END
    BEGIN "0 1"        Mat PavingStone  Con 0.00000  END
    BEGIN "0 2"        Mat PavingStone  Con 0.00000  END

Mat is a keyword for material, in this case they are paving stones. Con is the condition, or how much damage it has sustained; 0 means undamaged and 1 means it has been destroyed.

Find the cells you cannot build on and add the info to your question. Then you can edit the save file to change the material and reload the game.


These tiles are both water. As to why they have both been generated, I can only assume it's a bug. The lower tile looks different because it has a planning overlay on it.

They don't show up well in normal view because tiles on the border between two floor types never do show up clearly - but water is very distinctive in utility view:

Water in normal view

Water in utility view

Water tiles are not editable in the base game. Tony suggests a way to edit save files to correct this issue.


Some items can only be placed indoors - try placing a foundation, then place those items.

  • I don't think that is the issue. I cannot even place a foundation on that tile, and only that particular tile only. The tiles surrounding the black tile is totally fine. – ctjs May 23 '16 at 3:40
