I’m using the same picture (a dead end street, part of a tileset) and the same picture for all of them, and I’m just rotating them in piskel. For some reason, when I rotate one, all the others rotate along with it. For some reason, its changing the actual source image instead of the new one in piskel. It’s not duplicates (Although there is another glitch where a duplicate affects the original)
Are you renaming the images? If you don’t it might just replace. I dont use piskel that much so I wouldn’t know how that works.
