what happens with the choices and what are the choices with the warning? because that should be right before you start the event to progress the conspiracy storyline is and there shouldn't be anything stopping you from just saying your ready and getting into the event.
also just a sidenote, try both at day and night for whatever option you pick in case it's that. not saying it is but I've fucked up and completely forgotten some stuff is based around the games time cycle and struggled for like any hour lol.
