1) The download save-file for my survival world has been updated to reflect changes at the Hill Fort up to the end of Aug 2016. The link can be found here and also in my initial post (#1).
2) Several initial-post outdated Hill Fort screen captures have been replaced with similar images showing the Keep roof in place.
3) Gotta admit my initial post is becoming somewhat unwieldy. Something is wrong with it that can not be detected via normal editing. Attempting to put more of its screenshot subsections in spoilers to cut down on clutter, for instance, leads to text errors that take a good bit of time to correct and eventually reappear unless those spoilers are removed. I sometimes think to redo the entire thread from scratch, but at this stage of the game it's simply too much work.
