Mega evolution trainer error.

[bartyboy6]

I've recently added a Mega Typhlosion and to test it I've created a trainer for it.
but right before he send out Typhlosion I get this error.

What did I do wrong, I've created a mega the same way as any other mega evolutions and yet I only get an error with this one.

edit: I've tested it out with several other megas and they all give the same error

edit2: nevermind, I got it to work by downloading a new Pokemon Essentials and replaced my PokeBattle_Battler with the new one.
