Make the diggers in The Undercroft more meaningful

The Undercroft with its little diggers that move back and forth in the dig area is a fun, cute detail. But I found myself a little confused initially trying to make sense of the new layout and figure out where everything I knew was now located. I suggest a small tweak to that detail that directly relates it to one's businesses: instead of having 2 or 3 guys, put just 1 in the dig and place him on our level.

For example, in the attached screenshot of my Textile Mill, there is a guy on level 1 and another guy on level 3. Since I am currently level 4 (and 1/10), a single digger should instead be on level 4. And in the attached screenshot of my bronze production (The Keep), there are guys going back and forth on levels 1, 3, and 5. As I am level 6 (and 2/10), there needs to be a single digger traversing level 6.

It's a small thing but at a quick glance immediately tells you where you are--I do realize you can simply look at the highest filled level and any sublevels present above it to gauge this, but the man will draw your eye there--and reflects the real progress you've made.
