You can probably find an infinite amount of mistakes and secrets in the show...but it will never end...They do these mistakes just to annoy us, and they put the easter eggs in just to overwhelm us...I mean they spent so much time trying to get everything correct and to the exact way the shadows would be moving on the moon...they tried so hard in the first episodes, but we still found things that annoyed us or we had to point out.......but anyway, I have no idea where i was going with this but oh well...
