Hi stephankn,
Thank you for your comment! We can't find the disconnected way you're mentioning here. Please let us know if you find anything else. Also please note we are using the OSM Tasking Manager to map small squares one at a time. The areas we are working in now in the North East have not been completed, so it is not a surprise that some of them end. It may be worthwhile to look at the Provinces in the South that are completed. We would love your feedback on those.
Best,
Mohamed
