Guys, just telling you: Fractal next action (if he can fool the worker): editing all the schematics he will leave in the node, in a way they become not just useless, but could bring problems to the production line (as I said before). And then, there's Fractal need for letting his art among the things in his work. He will, no matter what, edit one of the schematics to resemble a Da Vinci schematics, if it was made in 3D, or something like that.
Don't worry about it, no one can be discovered by this action... The account I'm using don't leaves any log behind, and Fractal art is so dissimilar one from the other (and he never signs with the same name) that it can't be used to trace him.
