Playing one of the jobs while collecting my operator license, I accidentally reversed which layer was on the top, effectively creating a rotated version of the required shape. Nevertheless, the accepted count went up until it was complete, and the little floating helper icon over the vortex gate showed green (at least for a while, I could not get the screen to screenshot, and by the time I did, it had changed to a flag). Clearly the shape was wrong, and should have been rejected.
I have attached the save file.
