Some map packets state in the introduction that the Norman Conquest took place in 1044AD. It actually occurred between 1066 and 1087AD.
In the Ancient map packet on the map entitled "The Israelites Leave Egypt", the route taken by the Israelites is considered by scholars to be uncertain. Some scholars believe that they traveled further south to the tip of the Red Sea as we know it today and then doubled back up north. Others believe they had crossed further north by the Bitter Lakes, which may also have been considered part of the "sea of reeds" or "Red Sea".
In the Age of Exploration map packet, the map entitled "Renaissance Italy" has a word missing due to a text box that was accidentally resized. It should read "Kingdom of Naples".
