Switching balls in battle when owning more than 999 of one seems to be stuck

Holding R+Left Arrow works fine to switch going left, but holding R+Right Arrow plays the animation but doesn't switch to the next ball.

This bug has been around forever, but never managed to fix it.

This isn't really fixed, at all. I'll leave it open, maybe one day I'll fix it.
