Hello all! This is way how to disconnetct all players from server. (Mangos 2.3.3.)
1.Create new character and travel to ratchet
2.go on ship and wait when you arrive to strangleton
3.Port you character with WEH anywhere
4.Dont move with arrows! just look arround with mouse =)
5.Wait when your character begin fast moving (actually he is onboard on ship =))*
6.Then you will see loadscreen and thats all.
7.now after few relogs all players will be disconnected from game.
*if you character doesnt move try to teleport from ship and do nothing, just wait)
work on my server Mangos 2.3.3.
warning: Don't do that with your main character, because character will be bugged, and you couldn't play with it anymore.
good luck, sry for my bad english =D
