Some major problems

Okay so a few things.

One, it seems like some Pokémon’s stats are incorrect. During my 3rd elite four battle, my opponents lvl 89 chandelure outsped my lvl 89 mega feraligatr. Not only Should this not happen, the wiki has it totally wrong with the elite four teams and moves. Eudard didn’t have garchomp he had tyranitar.
And Yukis pokemon not only have items, their move sets are NOT those listed on the wiki. This info cost me the elite four run. I’ve included pics for proof.

There is a bug where the E4 use the Normal mode movesets and Pokemon when on Easy mode. The Chandelure outsped the Feraligatr because it has a Choice Scarf on Normal mode.

Ugh this is really freaking annoying. So the gym leaders also know what items you’re using as well?? Seems to be the case at least when trying to deal with Smeargle. I use a Chesto berry and he won’t use spore…switch to a white herb and he spores me. This is bs, honestly
