Half the fun of playing online games, MMORPG’s specifically, are the patch messages, this is my favourite in a long time.
The broken pieces of the Bridge of Khazad-dûm were backwards, with the longer piece on the west side of the chasm and the shorter one on the east. They have now been reversed. This could cause people who logged out while standing on the broken bridge to log on in midair and plummet to their dooms. This should teach them not to log out on precarious bridges!
