i'm sorry that makes absolutly no sense. i'll try again: o, i think i know what u saw after looking again. there' a silvery-grey block about 2/3 blocks counter-clockwise from the key-hole that looks like a section of white. you can see it at the start of the flash, but it goes into the position of the silvery-grey block. but the kehole definately appears due to other blocks.

lol sorry about that
