How many people in the party?
for the sake of easy math examples...
Lets say party of 5 people, that is 8 packs of Raveners.
65 XP for each Pack of Raveners..times the adventures threat level, again, for easy math, Im going to assume level 1 adventurers.
5 Level 1 Characters on a Menace II adventure have a TL of 1.
65xp per pack defeated times the adventure threat level, + the story XP rewards they completed, should give you a much lower number than you are seeing right now.
for just the Raveners it would be 325xp per player.
