Per 13.7 patch notes, "Map size is now limited to 2000 km by 2000 km with a black bar rather than crashing when reaching this distance'

I'm playing on a multiplayer server that was generated in 0.13.6 and it just updated to 13.7 today. I've been pushing the biter menace back from our mining outposts and ran into this black border that is maybe 3km from the map center if that.


This image shows how close it is to the map center. And it's generating irregularly, too.

Map generation was broken in 0.13.7
Hopefully we will have a hotfix update today.

Fixed for 0.13.8 (later today). This was caused by the change you mentioned. After loading saves in 0.13.8 the black chunks should regenerate as expected. Thanks for the report.
