I have tried editing map_regions to reposition the black dot for the settlement several times but i still get the same error message!

Is there anything you could suggest?
If the message gives you no name for the settlement, it is possible that some pixel remains with a color different from those defined in descr_regions.txt. The game identifies this pixel as a new region.
Check the whole map to find the lost pixel.

Or alternatively take the latest working version and repeat the process. Sometimes it works.
Good luck.
