I found...well, something. I'm not sure exactly what to blame for this, but here goes:
In Alice Sub 4, I took Lily to the goal. Normal enemy goalie encounter screen. I chose to dribble.
Then it got weird. It gave me a message balloon in Japanese, along with a tackle screen complete with tackle noise. There was no tackler sprite on the screen.
"Lily White dodges!"
My thoughts: Sweet, free goal!
Then it gave me *another* Japanese message balloon, and I got dumped back onto the field screen without shooting. Lily still had the ball.
So, I moved Lily.
Immediately, another enemy goalie encounter screen.
After that crazy stuff, screw dribble, SHOOT THE BALL.
Normal goalie can't reach, score, and congratulations screens.
Apparently there must have been some sort of phantom defender generated or something. There were a couple defenders in my general area, but they were eating my dust.
Hopefully this is replicable so someone can figure out just what's going on in there.
