How Do I stop Edited Areas being relocated to Africa?

Submitted by Malcolm MacGarvin on

So … I'll be working on refining the shape of an area, all looks ok. I save the edits, get a 'success' message, open the site and find it now in Africa, even though the GB Grid Ref anchoring (I assume) the site appears ok?

See screenshot. Has anybody else experienced this and - more significantly - found a way to stop this happening?
