Accidentally dropped boulder in wrong hole in the distortion world

pokemon-diamond-pearl-platinum

In the part where you have to solve the boulder puzzle, I accidentally dropped the first boulder in to the wrong hole (the one to the left of the boulder). Is there any way I can undo this action?
I do not have a savestate from before this happened.

You can leave the area then come back, OR save and reload the game. Both ways the boulders will be back to their original positions.
