I hope someone can help me with this because it's getting very frustrating. I've been playing this with a friend and we have always played together doing exactly the same things. Each night she gets more and more XP than me. She's now around 85,000xp ahead of me. We did a mission tonight and I get 50,000xp for it and she got 56,000xp. What's going on? I thought we should be getting the same.
