We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
I think it might have to do with what your current level is. At first I wasn't getting any arrows back. Then as my Archery level increased I started to collect 1 or 2 here and there. Now I can recover anywhere from 2 to 3 arrows off the dead.
I also read in another thread that as your looting level raises you start to get more loot out of things such as chects and barrels. Maybe arrows work the same way.
