The icon for Furniture and Decorations does not highlight when it is selected, even though the correct pane is opened. This is the only icon in the list on the left that doesn’t work, excepting the “Undo” button which has no associated panel anyway.
The furniture and decoration button doesn’t highlight but selecting an item within that section does, but are you running your game with a 3rd party mod? your lamps are red? didn’t know any mods worked with this version.
Ah. No mods. Those are Fine quality lamps. In the new version, when the carpenter levels up, he can randomly make higher quality versions of things 
while not wanting to sidetrack, that’s so cool! 
my lazy carpenters are all adequate level, but are apparently not very “motivated”…
