Not really a bug, but a usability issue.
Usually something like an NPC you can hit [f] to talk to them, then [f] again to close the window. However with the crafting window hitting [f] to close just re-opens the window.
This is most problematic when going to talk to the NPC next to the crafting station to buy supplies. If the player is too close to the station, hitting [f] brings up the wrong window and it’s a pain having to use the mouse to close it and then reposition the character and hit [f] again
