Pokemon Platinum keeps crashing after sprite swap

[RavageHero]

Long story short, I am trying to do a simple sprite swap within Pokemon platinum.  I have already created a custom trainer script for the area I'm in, and the battle starts when i talk to them.  The problems begin once the battle begins though.  I replaced Cyrus' sprite and scripted the battle to use his final battle team.  Immediately after the G disappears after the battle start transition, the top screen turns orange and the game freezes. I have tried everything, and I cant think of anything else.  If anyone has any idea, I would greatly appreciate it. Thanks.
