some of us leav e our beers in primary for a month or more, on purpose, skipping secondary and opting for a long primary instead.. Remember, your beer isn't FERMENTING that long. A beer will only ferment til the yeast eats all the sugars. After that the beer is conditioning.
So no there's no such thing as "fermenting too long" because a beer only ferments as long as it needs to.
