Neue Version 6.0.21 (07.12.2014):
v6.0.21 - Fixed a bug in the option 'Edit Providers/Update Providers' which failed if there was an entry in the RouteProperties.xml which was empty, i.e. both Provider and Product were empty. Changed the 'Remove Duplicates' option in the various 'List' forms to once again display the type of file in the 2nd column, e.g. Scenery item, Loft item etc which is needed for some options such as swapping one item for another.
