"Invalid species number" error when adding more Pok?mon

"Invalid species number" error when adding more Pokémon

This is a very straight foreward problem I got right here.

I added all of the Gen6 Pokemon in the "pokemon.txt",
and tried a simple pbAddPokemon script for one of the new ones (Pokemon number 716) and got this error message:

Message: Section122:861:in `__mf_initialize'The species number (no. 716 of 649) is invalid.

Clearly I have to increase the species number somewhere to match the now 720 pokemon.
I was looking for quite some time and didn't manage to find it...
Maybe I'm just simply looking in the wrong place but yeah, I hope that someone can help me. :)

Did you save your changes to pokemon.txt? Did you compile the game after doing so? Did you edit the correct pokemon.txt?

I was already wondering how you could manually compile because playtest doesn't seem to do it for me every time

If you play from within RMXP, then ordinarily the game will compile itself automatically if it sees a PBS file has changed. However, you can hold Ctrl at the start to force it to happen, just to make sure.
