I was shooting yesterday at my block. I pulled the arrows out and walked back to my 15 yard mark. I went to nock the arrow and noticed that the nock wasn't there. I examind the arrow and found that it had cracked. I figured that this would happen if the arrows had hit into one another, but they didn't. Does anybody know how it could have happened. Is there anything i can do to stop that from happening or is it just the name of the game.

It was a vaper arrow by blackhawk.
