I went on a housing tour last night and came across a house with one of those rideable merry-go-rounds. Naturally, I had to ride it. I also went through all 4 views. I think it was the Wyrd House, not positive on that.
When I got off the ride, my housing tour buttons had been replaced by the fishing and gardening buttons. I could not get back to the housing tour.
So I used the world door and went back to Wizard city and back to the housing tour house in the commons. Went back into the tour and the buttons were still the same. No housing tour buttons, but the gardening and fishing buttons.
