You have a troll on your game.
somebody is entering the game opening multiple windows and playing different characters in all of them.
3 or 4 characters at a time, killing everyone and siting on the wood for gold store, so nobody else can effectively play the game.
This is usually done because a rival game maker wants to reduce your users by making the game unplayable or that this guy is just a big giant loser with a huge low self esteem problem who can't play the game without cheating.
The solution is to only allow one character per IP# and if no IP# can be found for a user, then they can't play.
Just to let you know you have a troll on your game.
