Yeah, like that particular GM warped someone to the 2nd floor of some house in Hugel, drop a LP, change the save point to the trapped location in order to stop bwing escape, then set up large amount of static defenses and monsters in a zoomed-in indoor map watching the server come together in a struggle to rescue their trapped friend. That is absolutely unacceptable!
... Heard that from a friend. I have no knowledge of this event personally.
