Minigame stuck

[Sgt. ???]

Ok when i was playing sure its fun to have minigames but then some noob was bored just because i was working on my build and he made a minigame and then i banned him for doing so but his game is still there and i tried to start my own but it says game color taken

Tell him to end or ban, and then, if he dont, ban, and use a different colour

I do he came back and i told him to end it and he said he couldn't and i said i banned him also even if you change the color you get the same answer"game color taken"
