So I noticed the new gray broken gear icon that signifies damage (screencap attached), and the text notification, but I can't find a way to actually repair it. I'm going to continue until it's completely broken and just replace it, I guess. Does a way exist to repair damaged modules? The text implies that all I need is timber. *edit*: Mystery solved! It's a spontaneous job, just like farming and hauling. One of my colonists grabbed a log from the stockpile and hammered it back into shape.
