[Not a bug] Building fires out of line of sight

[Pengu]

Pretty much what it says. You can build a fire with your back turned to the tile the flammables are on.

I found this out when the cat wanted to play with me and burned up 90% of my possessions.

Not a bug, there's a reason for this exception:
Building a fire needs to be allowed even if you don't see the tile. That's because otherwise you couldn't build a fire the pitch-dark winter night because of "select the direction you can see".
It feel funny to do it behind your back, but surely a master woodsman can do that also
