Almost happened in the last Warhammer session I was in. DM made a door that had three locks depending on knowing alchemical symbols, formulae, and the geocentric model. Because the GM forgot that Warhammer doesn't have a flat "magic knowledge" roll like Arcana in D&D 5e, the party mage doesn't know anything, the rest of the party was illiterate, and everyone got so frustrated that everyone except my character tried either breaking the door or entering through the window while the wizard was still home and foiling their attempts. To our credit, we were able to figure out the first two locks with trial and error, with the first being a very simple balancing of the four elemental triangles around a plus sign in a plus shape, and the other being three symbols in a vertical line, the problem was seven symbols to be arranged in a circle. After my party face character shook herself from her puzzle frustration and realized that the wizard is actually home, she just asked him for what we came here for, he was cordial about it, and we left when we got it. During that time, the GM gave the solution (because Wizards are assholes that love to brag about their genius to the stupids) which taught us that in geocentricity, neither Venus nor Mars are closer to Earth than Mercury is, and the sun is between Venus and Mars because of course it is.
