So I know that script runs one by one line by line
and I know it takes a tiny bit of microsecond to run
so basically I have a round script that moves every single block the players has built from one folder to another folder
the problem is that I have a script on player removing where it removes the players folder with all the buildings on it
is it possible for the player to leave just right on time so that when I do :GetChildren and I try and clone the players folder to another folder
the folder dissapears because of the player removing
Thus erroring and ruining and stopping the entire round
and stopping my game?
It's almost impossible since it take less than 1 millisecond to move a block parent to another instance
So I can say, you do not need to care about it except the delay is big, it is redundant to prevent it because no one use a FindFirstChild or pcall wrap when moving a brick parent to another, since that waste data and I'd recommend you to not do anything about it
