I just looked at my "Hidden Months" map today. I narrowed it down to my resident county, which yields only one cache.
The problem is that the map then shows a zoom in on the cache. That's ok, since it does not need to show any other caches. The zoomed in map, however, is not particularly helpful since it only shows some obscure road name that I don't recognize. I thought it could be remedied by zooming out. This is where I hit upon what I consider a bug:
Zoom out does not work on the map if there is only one resulting cache.
It turns out, however, that if you pan the map first, the zoom out functionality resumes. It took me a while to figure that one out.
I realize that this might not be top priority. I just thought that it maybe one of the easy ones you can look into on a slow day :)
