"The evening before the Grand Exchange was installed, a player was casting alchemy on items in Varrock's west bank when he received the mime random event. Rather than complete it, he logged out. Between the time he logged out and the time he next logged in, the Grand Exchange was added. Along with this change, Varrock's western bank underwent a major upgrade, where it was expanded, given bank booths on both sides, and had its parameters shifted considerably. When the player next logged in he finished his random event and was returned to the exact same spot he was before-hand...which now happened to be a spot behind the bank counter!"
