is it possible to increase the time to 60 seconds? if a player afk there is no big chance the player will be back during this 60 seconds but there are many cases when you are not realy afk, eg:{NOTE: If a GM suspects a player is AFK, the GM will say something to that player. The player must respond to a GM. If the player does not respond within 20 seconds, the GM will assume the player is AFK and kick the player.}
