I had a really weird experience yesterday. I signed up with Zwift, meaning to do the clubrun (as a meetup, obviously). I tried the introductory "hilly loop" a day or two ahead, for familiarisation, but got called away to real life before I'd finished, so left the ride part-done. I didn't have enough free kilometres left, so I paid before the run.
Yesterday, I clicked on the meetup in Zwift and was whisked off to another world, but it was back to the hilly loop. I was getting some updates from the meetup, but not many, and I couldn't see other riders. So I ended up doing the loop again, by myself. But I ran out of timed meetup (for the clubrun - I could see the remaining time) before I'd finished the loop. So I reckon that every time I go back into Zwift it will be groundhog day on the hilly loop, and I'll never finally finish it.
