5th Gen Pokémon Error

I updated my game from Essentials 9 to 11 and whenever I try to battle any 5th Gen Pokemon, I get this error....

Exception: RuntimeError

Let us know when you decide to fully compile your game.

I could do without the sarcasm, thanks.

Even when I did compile my game, it still came up, so I had to end up changing a few things in my PBS folder.

And, once I did, it started to work, but another problem came up:

There are huge unknown factors here, which make it hard for me to give you the answers you want. You've edited Essentials (you're making a game), and you've "upgraded" it - odds are you've tried to patch up your game rather than transfer your changes into the latest version as recommended.

The answers I provide work for Essentials. Any problems are caused by what you've been doing to it. You've most likely missed some of the code changes I've made since v9, which your error message does suggest.
