Just experienced this bug this evening. Basically, I got off the trainer and just sat down on the chair next to it while the trainer was still spinning. I grabbed the mouse and was waiting for the “I’m done” button to pop-up, but instead my avatar “freaked out” and it gave me an insane reading of over 3,000 W and the green jersey before finally popping the “I’m done” screen. I will try to recreate again tomorrow morning. I also have a screen shot if you are interested.
I am using a Lemond Revolution trainer with a Wattbox. I know that it is not officially supported, but apart from this particular issue, it has worked flawlessly. I am close to level 8
