I just finished the Daily Challenge (Seoul) and ran into a unique station. I've never ran into this before. It had mainly triangles and some other stuff. I built a line to a triangle station but the train picked up only the 2 non-triangle "passengers". I put another train on that station and it left with nothing. I tried this two more times with no results, the triangles refused to be picked up, no matter what a did, the timer ran out and the game finished. Are there deliberate stations being placed to finish a game after a certain point threshold is reached or for any other reason? I am the current leader (Daniel R Lenz). Was that a trigger?
