Hope this isn't considered necroposting, but I have a suggestion for a very important new rule. If you have the paranormal pack, you are required to make one of the hidden rooms a séance room, as she was obsessed with doing that and that is literally how she "received" messages for how to build the house.
She is also required to "communicate with the dead" every night at midnight (which is when she held the seances).
This is a really cool idea, and I plan on starting the challenge today. :)
