That's the thing; when I start a new colony there are no issues in gameplay. It's only when I try to load into a save that these errors appear.
I will have a look at expanded roofing though and see if disabling it or moving it around has any effect.
Edit: Moving and disabling expanded roofing did not solve or change the issue.
I did however discover that if I hover the cursor over a large area of unexplored mountain, the bottom right UI reappears. The pause/unpause/speed buttons are functional, however all other buttons do nothing. Tool tips generated from hovering over elements remain even when the mouse is moved away, or other tool tips are generated.
Sadly I am too dumb to determine what, if any, use this has in determining where I went wrong.
