In the latest version of the game 8.2 test, when creating a new world, for some reason the tree house does not appear. I start the game on the 32nd day but there is no house. Although if I start the game before the 21st it will be there. What is this and how can I fix it?

It might have been changed in the update which would mean it probably won't show up in a ongoing save. This was the case with the killshed when the last update dropped i think.
