My Mankey wanted to learn Karate Chop, but needed to forget a move.
First move in the list was Fury Swipes, second was Scratch. I then decided to swap the position of these first two moves.
Then, i chose to forget Fury Swipes which was in first position in the forgetting move menu .
Instead of forgetting Fury Swipes, the move forgotten was the one in first position, which was Scratch.
Not a usual thing to do, but wanted to warn anyway.
