Check out the second bullet, "Explore a mysterious new and secret location"! I’m pretty sure that this event has something to do with the rockslide at the Mine. If you remember the Halloween party, it’s the same area where Gary’s Secret Lab is located. Maybe Herbert is trying to get into Gary’s Secret Lab to steal some of his inventions in mission 11!
If this is all right and the new room will be created, the blank TV in the HQ will be filled! If Gary’s Secret lab does become a new room, it will probably be only for members since it is listed under the membership events page.
