[solved] L5 Livingston, Scotland

This locked roundabout is clearly completely bust (looking at Summer of 2012 Google Street View imagery there is still a roundabout here).

Nice one. So you can still join to the roundabout without updating it and thus not requiring an unlock? The update dates for the segments are still from 2011.
