I have a project that has a sprite that follows a character, at a set image point. I've got it set that:
spr2 | While on Screen: Set position to spr1 (image point 1)
spr2 follows spr1 fine, except when spr1 moves, it defaults the position back to the centre of the image.
I'm not sure if this is a bug, or there is just something with my setup.
