In the Double Battle against Faba and an Employee, I use Dugtrio's Earthquake, KOing Hau's Raichu. He then sends out Primarina. I then go into Bag to use an item, and the game freezes. I am playing on an old 3DS.
Specifically, the music continues to play as normal, but the game no longer responds to any buttons. It doesn't respond to the soft reset combination (L+R+Start) or the HOME button. I have to actually hold down the Power button to escape this.
This has happened twice now (and I've only tried twice). I've attached an image of the screen it freezes on.
(Sorry about the giant attachment. I don't know how to put it in a spoiler or shrink it, without resizing the image before uploading.)
Edit by Torchickens: That's OK SnorlaxMonster. I've adjusted the size of your image and left the original here.
