I pulled down a copy of the latest backup and generated the following map, and I added an overlay per
709's suggested trims above.
As
Elysium said, you can see some black spots in the regions to the left because those region files were wiped last time and they haven't been explored enough to be filled back out.
What say we about this arrangement? Should I drop the two chunks with missing areas or keep them? How does the rest of the map look?
