So, I was roaming about in Number land Calls area where I found a Dinosaur Bone. I inspected it and moved on but lost the horse in the fall.
So I didn't want to run around on foot so I used the Auto save option to reload a few minutes back I discovered the bone.
The issue occurred that the bone I had inspected previously was shown on spot but now I am unable to Inspect it however close I am to it and see it through eagle eye.
Similar case occurred about about the Rock Carving at Mount Hagen.
It's my 2nd play through and this is frustrating as I can't make new trinkets, exploring would be all wasted and 100% game completion will not occur. Someone please help.
