Has anyone ever had a challenge disappear? Mine was to double my goal 14 times, which was really tough between work and rain! On August 30 it disappeared but it showed up again before midnight. That was day 13 and I made sure to go out on the 31st. It never showed up and never told me I got it, and now it's still not in my list.
It is quite flaky for me!
