Has anyone who opened the vault given a tour to Cassidy afterwards?
edit: I shot out all the lights, turned on the stove, vacuum, generator, and both tvs, then shot the door bells a few times and it opened. Don’t know what the order is, or if all of that is necessary but it worked. No need to ring any other bells besides the house for sale.
edit edit: Cassidy tour provides no new info even with the vault opened, he just doesnt mention if you can open it for him.
