I've just checked my points value chart following discussions on bows and such like, and spotted a rather, erm, silly mistake. Basically I've got the longbow in there at the same points value as a (composite) bow. This has a 'ripple effect' on crossbows, which also need to go up to keep their 'differential' correct over troops armed with a longbow. Doh!!! So, the points value for all troops armed with longbows and crossbows (or their equivalents) should go up by +1 point. Sorry!
Fortunately this doesn't effect many lists in AoA (which is probably why it happened in the first place): Skirmishers armed with staff slings or crossbow go up by +1 pt in the Alexander, Late Roman, Byzantine and Norman lists; longbowmen and skirmishers go up by +1 pt in the Indian list; crossbowmen go up by +1 point in the Norman, Crusader and Ancient Chinese lists; and Samurai armed with longbows go up by +1 pt in the Samurai list. Finally, add +1 point per crewman with a longbow to the value of each chariot or elephant in an Indian army.

PS. You can't spring these points value changes on an opponent at the start of or during a battle! Make sure you tell them well in advance (at least a day or two), or stick to the values in the book.
