So I was hitting that same trail again today. I went to climb some rocks in high grass and my buddie who was filming siad it may have cought up in some type of fence. After that was making the clicking noise. Im thinking something broke. As im currently tearing into it I thought Id post a vid of it in case someone has a pin poin of what the problem is.
