Running with a friend and he can see them but i cant?
When the patch came i found a few but now i cant see them at all..
I did the same thing. I went there, and thought I was making out like a bandit from the chests.
When I went back to the same area again, I saw almost none, and put it down to bad RNG. :)
Once you've looted a specific moss-covered chest, you'll never see that one again. :(
