Yeah, I was looking at the city centre a little before the import,
wasnt sure who to blame. (Google maps also use naptan data, so if you
compare the points with the aerial view, you can see they're a bit
off) - We still need a good way of aligning them though without
referring to them.

All data was uploaded as of about 10pm last night. If you find any
elements that look like glitches in the conversion, please report them
to me.

The idea was to delete it.
