I did it and it's solving here fine. Also the simulated image is fine. I can't say why it wasn't solving there on the simulated images :-(

I looked at that thumbnail and thought it was "salt and pepper noise" but it was late in the day I guess. With the 3 deg field, it is just a hell of a lot of stars.


You should be able to turn final image plate Solving (General tab) back on.
