Wordpress 3.6.1, Autoblog 220.127.116.11
Multisite network, autoblog being used with 4 feeds from the same network. Autoblog is set not to sort into a category and make any that are necessary.
In some cases one of the duplicates is missing a category, but in sets of duplicates this is not the case and each dupe has all categories and meta tags, and no differences as far as I can tell.
There is no issue with the feeds themselves.
