I just uploaded a Rom with the hiker in the dragon valley fixed. As expected, he had the corrupted hiker's sprite but now he has the working one. Everything should be all clear. Other then the Legendaries not disappearing & the re-occuring events, the hack is pretty much bug free up to this point. Thanks for playing everyone & telling me each of the problems.
edit- where exactly if groudon present in the inferno mountain....plzzz say
