> (the run trick) works by first standing on a square before a trap, and then running across the single square that has a trap, in order to end up on the other side. Because running causes the player to move over two squares in a single tick, this causes the game to never consider the player to be on the trapped square.

This is like Programming 101 for player position updates, to avoid them running or jumping through walls. A classical novice mistake. I'm surprised to see it in such a mature game.
