(A) glitch involving a freeze when you deliver mail to the Wingull on Route 13. If a package is delivered when there is heavy rain, the screen fades to black(?) and freezes. You can't do anything at this point, so you have to reset the game.
I haven't tested this and wonder if true if it's on video yet.
