Hello,
I want to report the sinnoh underground path bugged. Since about 2 days, it is nearly impossible to win, since you are not getting NPCs wanting to battle. Because of this, you only get clues from NPCs wanting to get an item or shown a pokemon. One type of NPCs give away a useful hint, but the other ones don't.
Then, you have to choose between about 8 different holes to drill (western or eastern side), which makes the whole quest a waste of time and resources.
Thank you.
