I was messing around with the scratch vector editor and found something strange. See inside, then go to the vector editor (costumes), and drag the stick(s) around. There seems to be an infinite amount of sticks, until you press CTRL+A (Chrome), then backspace, or the delete button. Also, I did not copy and paste that stick over and over again. If I'm not mistaken, that would place the stick in different places every time you paste it because Scratch doesn't want you to paste an object on top of itself so it's easier to tell there are two of the object (or something like that).
