This change seems to have left the huge heath area unbounded - this causes corruption in my GPS device and associated software
Could you close the area?

Note: This caused issues for OFM map which couldn't render correctly due to unclosed polygon

Comment above, I mean OFM export to basecamp

Not this changeset exactly but this heath area is not closed and will not render correctly in Garmin Basecamp (large area coloured pink at certain zoom levels)
