I edited this to correct the full situation last night on the computer, which is far easier, and what I shall do in the future. Anything that doesn't appear in SC I shall do on the computer.

Andy, I can only see the gap in the A170 at a zoom levels 16, 17 & 18, it's there at all others...?!
I'm sorry, I didn't note any new signage, I shall have to return to check.
