Some freaky error....

[fenrir]

I've been getting peculiar errors when entering a battle called from an event.

It only happens sometimes, and only to that event.
The event is a cutscene, and it shows a battle in the cutscene. When it calls the battle (Against an Efreet) it crashes and says something along the lines of

RPG_RT.exe Access Violation

This only happens sometimes, remember.
