I also discovered this problem. One of the options was valid SAN requirements, which I clicked. After that I could not choose another option. I reloaded from the last savepoint, skipped ahead and this time avoided that SAN option. I was able to click other options and the story progressed normally. In the study/library later, she had a SAN option, which I avoided. I'm guessing that SAN is just placeholder text for something that isn't working or mislabeled. Either way, if I am right I'd suggest avoiding clicking on any option that says valid SAN requirements.
