I’ve noticed a massive number of typos in the Monster Manual for the ability scores of the creatures listed. Ogres are a great example – a +2 bonus for an Intelligence of 4? +14 for a Strength of 23? These errors are all over the place in multiple entries, almost to the point where the mistakes are the rule rather than the other way around.
I’m sure they’ll post corrections to D&D Insider once it is up and running, but wow, those are a lot of mistakes.
