You probably boiled off some of your hop aroma, and may have increased your IBUs slightly. If you're dry hopping you might want to up your quantity by 1/4-1/2 oz. I wouldn;t worry about the any increased IBUs because A) there's not really anything you can do about it, and B) because unless it's a very bitter beer to begin with the difference is probably below- or close to the threshold of detection (5 IBU), which is the sort of variation that can happen from batch to batch anyway just from the dozens of variables we have to deal with.
Stop using so much caramel malt. Your beer will thank you.
(yes, Carapils is a caramel malt...so is Special B)
