This is the funniest bug I have yet found in my game. My first base. Only some of the walls get build and suddenly after I clicked on a wall this message comes up and my builders charge in, I am delighted as it looks like they are going to finish it at last… not so fast though as they don’t build the floor (yes I am sure I placed a floor) … they dig it up !! lol.
What is the strangest thing to happen to you while building ?
