Don't feel dumb it took me days with help to find the hidden floor lock in the below ground area with the three skeletons just down the hill from Jacksons farm in Broken valley.
I looked thru that broken and bent door many a time and said there has to be a way to get to that chest surrounded with gold. Except I thought I'd get all that gold.

That is one of the first places I found there.
So after that multi day brain fart I resorted to looking at a walkthrough for any hidden or puzzle stuff. I want to play a game not be baffled for days.
