To replicate:

1. loaded an .osm file for England into a feature dataset, and 2) used Create OSM Network Dataset tool (DriveGeneric.xml) to create a network dataset. It completed without errors, but took quite a bit of time – and the progress bar was reading 100% for many hours.

Progress bar should more accurately reflect progress, and not indicate 100% if not near finished.
