Hi,

This is typically a late afternoon chore. I'll schedule it for the next couple of (rainy) days. I've looked a bit, there's really no good way to split but along one winding road and a large complex inner area which will cut out many members already. as then it becomes outer, Still recommending to try out JOSM as it's a rarity such complex MP relations can't be loaded in one go. It will tell you exactly where the shoe needs tweaking. When these issues appear it's always ID, never seen a JOSM mapper being flagged that I can remember.

ciao
