Completed the hillclimb last night. During the ride I missed getting a picture of the Yeti crossing sign so I turned around, took the picture and continued up.
Unfortunately, I think that turning around caused switchback 11 to not complete (no star). Pretty sure this messed up my achievement of completing the ride. At the end of the ride, the counter showed 20/22.
Nope, no spinning prize wheel at the top. It’s not a big deal for me (except for maybe missing out on the chance for a laser helmet). Expect some people to be pretty cranky about this bug.
