Did you ever get this figured out? Not sure if it's intended (not finished) or an issue.

Hi , indeed that corner have been blocked, the other area's are in progress. Next week i'll upload a complete dress-up for the available/playable part of this map(africa), when that's completed (prob. 2 uploads needed) i'll re-start those blocked out area's. (south-america, europe, north-america)

Thanks for the update. Is there a map that refences which area is which (not sure if I missed it). I'm building on an undevoloped island (roughly lat 62 / long 47). What will happen to my base when this area is updated?

The island where you are at is called south-america , i give it a rough 4months before that part will get updated, When this happens, your building will be still there but probably with parts inside the landscape and part available or can float in air, that part still needs some sculpting work.

Thank you for letting me know. I'm sure I'll have a server wipe by than so it shouldn't be an issue. I appreciate all of your work and efforts with this map. :)

Thanks for the heads up @ -NRU- Tjoepapke
