The battle background for older enemies are showing up fine, but if I try to copy and paste those or add another enemy...well, the battle processing runs fine in that you can fight them, but there's no battle background, just a black screen. The backgrounds appear on the Battle Test screen, but not in the game itself.
I'm using a few user-created scripts: Hermes, plus Amaranth's Commercial Game Kit (there are others too, but since the 'working' enemies - ie, the ones where the background appears - were added after these scripts, they're probably not the problem).
Does anyone have any ideas? I'm really not a scripter so I don't have a clue how to go about fixing this Any help would be gratefully received.
