Round Only Works One Time

[JordanGetMeBackmyAcc (Yong)]

so i made a round system and after the next round everything just breaks, how do i fix this?

theres no errors or anything it just breaks

spawn(system)

[DasKairo (Cairo)]

You run it in a while loop.

while true do
    system() -- I removed the 'spawn' because keeping it would cause them game to crach
end

and also, please use task.wait(), wait() is deprecated
