hello, i'm making a factory game and the conveyor belts aren't working. the conveyors are clones of a “machine” sprite, i want the conveyors to move ore (which is also a clone but of a separate “ore” sprite) that comes out of a drill (which is also a clone of the machine sprite) 25 steps. but it's not working the way i'm doing it. if anyone could help me with this issue that would be great, thanks.

Script that's not working (in ore sprite):
(Machine sprite is called place in this image and ore is called item)

We need to see the full project, since we don't know what the list dir contains and other things.
