This has been bothering, and I think this should be known:
"Y HAV U NO RELES THETA EMERALD?????"
Ahem:
-when there are 2 TM item overworlds on 1 map, it will only load 1 TM (i.e. TM106 (Skill Swap) is supposed to be in the beginning of the first Mt. Pyre summit map, 24.21, and TM61 (Will-o-Wisp) close to the end of the map. But, both overworlds contain TM106)
-At certain times, like buying an item, or receiving a TM from someone, makes the player turn into the player of the person they received the item from, or bought the item from
-Some Pokémon have no front or back sprites (like Cosplay Pikachu, Mega Alakazam, Mega Gyarados, Mega Mewtwo X, Mega Mewtwo Y, Mega Tyranitar, Mega Swampert, Mega Medicham, Mega Altaria, Mega Latios, Mega Rayquaza, Mega Lopunny, Mega Diancie)
-Updating Battle backgrounds and play through of the game
So, please be patient, and have a nice day :)
