China or any other big country do not offer "land only" boundaries
I noticed while ago that I'm not able to download any big country if "Land Only" selected - there are only islands in the file and mainland boundaries are skipped. This happens no matter which admin or simplify level selected. What could be this issue about and could it be fixed
Thank you
Switch database. OSM-Boundaries provides data as is. If the data is broken in OpenStreetMaps planet dumps, then it's broken in OSM-Boundaries. This is the reason to why we provide historical data. The coastline doesn't work properly with for example the dump from 2023-04-03.
