I rode a few laps in reverse on Watopia this morning (23/10/15) and I beat the best Sprint, KOM and full lap time but never got a single jersey. My time was also not added to the leaderboard. But my lap times must have been recorded because as I went through the various sections again it would tell me my last time. All of which should have been on the leaderboard.
I also noticed another ride pass me on the reverse KOM climb, but he did not appear on the leaderboard either.
When I rode the “normal” way around my times seem to appear on the leaderboard, so I guess there’s an issue with the reverse timing.
