I've seen where some people wondered if the main saucer ring on Discovery might spin. In the engine room when Burnham comes up to Stamets (right after the "lurker" line,) there's a graphic displayed that appears to show the saucer turning slowly. I took a screenshot of it, the time stamp to see the spinning starts at about 21:36.


. I agree we are gonna get more issue with the drive and some massive "oppsies" as they really should not be playing with that.
