I have a mine going and the iron ore is about 3 cells into the tunnel on the floor.
I have the Mining menu option from right clicking the tile but nothing happens.
I tried Dig Tunnel, nothing because its a floor tile.
I tried Dig Tunnel Downwards, and it grabbed some Iron and Rocks until the slope matched the joining tile.
So I am guessing I can't actually Mine the ore because its in the floor?
The only way to actually mine ore is if its a wall?
I've searched around but after reading through 10 pages, gave up on the search.
Thanks for any help!
