I’ve not been on Zwift much recently but I just hit a bug of some sort that may or may not be 1.34 related.
I joined Maria on Sprinters Playground in Makuri. After a couple of minutes my Sterzo disconnected (possible other thread). Maria sped off as I tried to resolve this issue but I just got back on to follow the route anyway.
The route progress bar was visible but was alternating between showing the route as complete or counting down - but in metres rather than kilometres. I’ve only seen the latter in the final approach to the end of a route, but this was with 4,000 or so metres to go. I’d then get near a junction and it would stop updating, showing 0% (complete) again. This repeated a few times and didn’t seem to be related to sprint segments. I was still on the correct route.
I have some screenshots taken at random points showing the behaviour which I can upload.
