I have no issues with anything. I was a bit concerned when I first heard there were hidden challenges, but they weren't all that hard to find. The length of it was actually great for me as it gave me stuff to do, but if it's going to keep being so long, I'd actually like to see more challenges because if I would get a month's challenges all done the first week, then I'd spend the rest of the month waiting, so I don't know how that could be fixed or whatever. Maybe do a few challenges each week instead of all the beginning of the month. That said, if it goes back to being just a couple months instead of as many as it was this year, I'd still like for there to be around 35-40 challenges, but I can see how it might be an issue for other people. I myself, don't have much of a life, so I have the free time to do these things over the course of 4 months, but I can see how some people would rather just get it all done in the span of a weekend or something.
Anyways, as long as there's a hunt, I will participate. No matter what the stipulations are. I just find it fun.
