What I mean is ever since I caught the shiny Ho-oh, if I travel to Pathless Plain, Nameless Caver, or Trackless Forest, I can't interact with the portal and challenge the legendaries that are in that specific area. I have challenged and beaten the Elite Four and still have the problem. I don't think that the time of day should affect whether or not I can or can't find any legendary, as each legendary in these areas have a set time of day that rotates 24/hrs as a whole. It's not that I can't find the legendary that I want, it's that I cant find any at all. I was wondering if this could be a street pass problem, as I could've picked up mirage spots that other people may have completed, causing a bug to make my game believe I've completed them too, but that's just a hypothesis that can easily be proven wrong.
