[Error] crash at alternative form Pokedex

[Loliberto]

I added some regional species to my game all of the works how the should except Budew, the game crash when I see it's Pokedex page.

Here's the error. I have that plugins but don't know if their related.

Spoiler:

[Pokémon Essentials version 19.1]
[Generation 8 Project v1.1.2]
[v19.1 Hotfixes 1.0.7]
[EBDX v1.2.6]

Exception: NoMethodError
Message: undefined method `[]' for nil:NilClass

EDIT: It seems that this only happens on regional dexes. NatDex works fine
