[Talk-GB] Mapdust Newbie Question

[Paul]

I know this isn't strictly an OSM question but after hearing on here 
about Mapdust I thought I'd have a look but so far I can't seem to work 
out exactly what most of the bugs are meant to be

Take http://www.mapdust.com/detail/157118 for example. This shows a 
start point on a motorway slip road, an end point on the motorway and 
has a roundabout symbol in the middle. The bug report says that routing 
on the roundabout is flawed. What roundabout?

Can anyone try to explain what this bug is meant to be? Of the several 
bugs I've looked at so far only one made any sense and the OSM data is 
correct so it's a false positive anyway. The rest just don't seem to 
make sense.

Thanks

Paul
