Another odditiy is that the Wiki is being updated and "rooms" or "locations" are being called "pictures". Why is that? We don't play a Picture. We play a room if it is inside or we play a location if it is outside. Puzzles still seem to retain their name...

I hadn’t noticed the change in terms, but you’re right about the semantics of it all!
