Alright alright, it's been long enough. I've spent a few days adding in Isle of Armor stuff. All the Gigantamax sprites are finally done, as are any legendaries released up til now.
The pbs files have been updated with the new moves and abilities introduced in the Isle of Armor, the new Pokémon introduced in the dlc were added into the Pokémon pbs files, and all newly reintroduced Pokémon have their updated movesets.
A fair warning is that a lot of the moves don't have the proper function codes. Most of them have existing code in Essentials for their effects, but some don't exist at all, so you'd have to add those yourself. If I've missed anything don't hesitate to comment and tell me.
