Hino-Arashi, there's something funky in Mt Granite.
I've ran into an Alpha Tyranitar, a Piloswine inside the cave, and a Beartic in the northern part by the beach. besides all being level 81, they all had the exact same move set. Stone Edge, Super Power, Crunch, Dragon Dance, in that exact order.
I'm pretty sure that's not supposed to be the case. It sounds right for Tyranitar, but the rest, not so much.
EDIT: did further testing. Every single pokemon you run into once you go inside the cave of Mt Granite, then the northern part by the beach? Ever single pokemone is level 81, and has the above mentioned move set. And a re all holding a Chople Berry.
Just to be clear, I was running around naked for this whole process in Debug mode (enitrely cause I was needing some rare candies to survive Mt Granite), and it's only inside the cave and the north beach. before the cave is fine, it's only the Alpha Tyranitar with the move set and berry. The alpha Machoke I caught in that same cell had different moves.
EDIT 2: and not only do they all have the same moveset, they have the same Jolly nature.
