If it's meant to be 7 then the line about the left-hand side weighing 120 lbs doesn't work, and a book is described as weighing 1/10 of a silver bar plus a feather, so that wouldn't work either. ^_^
Yeah, I realized this last night and corrected it-posted the fixed version of the puzzle in a devlog since I can't update the files until the jam is over
In that case I'd consider rewording the rock clue as well, because that makes it sound like the "weight of the two scales" is incorporating that 120 lbs into the calculation.
