This Plugin fixes crashes by exploiting the /teleport command by using too hight numbers. It blocks any teleport commands with higher numbers than allowed. Since Minecraft loads the chunks before executing the teleport event this is the only way to fix this.
Config
In the config you can edit the maximum allowed coordinate and which commands are checked. The message sent when any player tries to teleport further than the allowed area can also be set.
