Running algorithm does not detect infinite loops in running paths

[RMTEW FULL NAME]

Running algorithm does not detect infinite loops in running paths.

It should note where it turns, and which direction, and if it hits a duplicate turn, stop.

On reflection, not sure I really care about this. As long as players know they can interrupt the running, they can choose where it stops by doing so. Just wait until it comes round past the best point in the loop, and interrupt. Saves moving there manually. What I would do is make it easier to interrupt this, is perhaps let any key press result in a prompt asking whether they wish to interrupt the current action.
