Ok for those of you who think you are stuck in the jungle then follow these steps and you will get back to the shgip with all nine parts. This is how to leave look at the path if it looks to bend around a conrner then use only those paths as if you use the others they just take you deeper into the jungle and round and round making you feel ill LOL i hope that this helps those of you stuck in there. This theory worked for me and 15 other people i told so i thought i may as well share it here and help other finish the plot up to date.
It seems like they fixed the glitch... For me this part wasn't difficult at all, i expected something like the woods in ToW, which where really frustrating.
It might just be me, but I think this plot is the most boring one so far. I think they need to do a war like they used to do, with waves and everything
For those of you struggling to get the bone saw, simply go to the journal, go to the map section, and in your address bar, paste: javascript:doget(); That will get you the bone saw (Y)
