Hmmm...I never realised that the 3rd hut was not automatically detected like the rest because the builder(s) always never fail to find it and construct it without any effort on my part.

And for the garden, I didn't know you could use it up! Is it so since v1.0 or only starting from v1.1? Either I have missed it all these whiles or my villagers never get to use it up!

It seems that there are still "unsolved" mysteries within VS for me! Hurray!
