Hi David Thank you for bringing this to our attention. We have looked into the issue and have found that we have 41 missing entities in the 7.3.1 version of the places file. Some of these are highly visible places (such as your Alabama case) We have diagnosed the cause, are in the process of producing an updated version of the data and will make it available as soon as possible.
David Since my previous response we have made new downloads of the data available. Both versions 'geoplanet_data_7.3.2.zip', released on 2009-10-27 and (the latest) 'geoplanet_data_7.4.0.zip', released on 2009-11-17 have this issue fixed.
