You need to give more information before I can help you. Are you the owner of the minigame, what are the Leave Rights set to, etc.Also, in the future just post Slayer help things in the Slayer topic. Thanks!
Also, ending and restarting the minigame should resolve the problem.
Can you post your console log?
I was just on his server.No one, despite settings, can leave the minigame.Not via the leave minigame button or /leaveminigame.
function serverCmdLeaveMinigame(%client) { if(isObject(%client.minigame)) return; Parent::serverCmdLeaveMinigame(%client); respawnPartGroup(%client.brickGroup); }
