Well I think the biggest trouble is that when they do the mazes, guests are really overwhelming the guest rooms. This also happens in pin judging room contests (how many found you could not actually work a trade in one of the contest rooms). During non-event times, guests are dispersed throughout the kingdom in games, public rooms, and guest rooms. Teleporters are being used but in a smaller percentage.
Now, you set up a series of mazes between guest rooms, announce it as an event and over 2000 guests all try to log on at the same time, cram into the rooms at the same time, and start putting severe stress on whatever part of the program handles the teleporter command.
Although I appreciate VMK trying to utilize some of the Community Leaders to help create the mazes, I just have to question the wisdom of putting so much stress on the server(s) that handle that aspect of the game. The maze is a great idea but I just don't know if they have a fix yet to handle the execution.
