Pyramid: play button not restarting current bar

Not sure if this is a bug or a feature - Pyramid has started displaying strange behaviour with play/restart mode engaged on the play button.

Where before it would restart the selected bar as desired, it now restarts at an entirely different point in the sequence - what’s more, if I keep hitting the play button it will move forward in the sequence by a consistent number of bars (on this session it seems to be 4) each time.
