Stuck after Repack Ridge Arch

Set a PB on Repack Ridge today, and after the finish arch, Zwift put me back on my road bike, as usual. But then I just sat there in “Track Stand ■■■■” - all sensors still paired. Zwiftalizer showed no unusual dropouts or ant+ issues. Cadence, heartrate and power still showed in the data on-screen - but the avatar just sat there, not moving, doing a track stand.

Eventually I ended the ride (which saved and loaded to strava, etc. as usual), and then restarted Zwift in a new session, and had no issues at all.

Not a big deal, but very strange, and the first time I’ve ever seen it.
