When I open "Edit Attacks" the attack picture in the bottom right is missing, how do I fix it?

In the attack editor, a preview of the attack's picture will be displayed in the bottom right corner. You must first draw the attack picture in the sprite editor.

From the main menu, go to "Edit Graphics" and then go to "Draw Attacks"

If you have already drawn attack graphics, and you still cannot get them to display in the attack editor, please file a bug
