When trying to place something, especially in a corner or between two things, you got to play around with the placement using ctrl. Move it one bip that way or another until you stop hearing the annoying error noise and those awful red letters "That site is occupied!" and finally the sweet release of a plop met with a the warm glow of the beautiful construction you're about to build. You go about your day using your new contraption but at night you wrestle with the idea, "what if theres a better way?". What if instead of the game annoying me with that awful terrible obvious notification when that happens it can simply return the name of the object that is blocking placement. So instead you'll try to place, hear an error noise, look down and read "site is occupied by palisade wall". Aha! So the wall is blocking the placement of my smelter and not the stone mansion therefore I must move the placement in this one very specific direction instead of guessing.
More plop, less noise please and thank you.
