Hello Youtube
The problem is solved!!
Thanks to The Krazy Gamer _see reaction below
It seems you have to make an event with a script with: pbUnlockDex
to give the trainer the Pokédex.
But to make the Pokédex true you have to make an event with a script with:: $Trainer.pokedex=true
that way you will get the Pokédex and that it's true when you have a Pokémon ^_^
I'll make a video of it soon, just to make sure nobody else will have that problem again ^_^
(And of course thanking The Krazy Gamer)
