Yeah, I've had the problem before where it gives me options for an entirely different question but the correct answer finder picked the correct answer and I was able to get it correct. However, I've had it happen from "loli" characters(for lack of a better term) where they were short with small boobs and a thin waste, no matter what is asking, even if there is a mix-up the answer should be "small" backed up by that always being the answer when it will let me answer them. However, often it comes up and the answer key mod gives no correct answer and that turns out to be the case, even when I try picking other options. There is a 33% chance of picking it correct at random, I won't always stick with the correct answer and will try different options, over the hundreds of questions and answered at random, the chance of me getting it correct at least once is pretty high, but that isn't the case. I think we can reasonably conclude that the game is for some reason giving questions in which it doesn't recognize the correct answer as a bug.
