I am at the point where I can get regigigas in one of my current games. It wont appear for now, some poeple say you have to wait to the day after after you cought all 3 golems... I'll update you tomorow I guess!
I should get it by noon if its trully because of that... dang pokemon with complicated conditions to get :)
For some reason I can't pull my ORAS legendaries from the Pokebank back into ORAS despite having been caught there, I can put them in Sun\Moon if you have either of those. If not I was plannign on resetting my Ruby anyway to farm for better Legendaries anyway and it would only take a couple days to get a new one.
