I am trying to find a method for bringing in all of the comments from a Blogger blog. 3121 / 3121 posts came just fine, but only 50 / 47924 comments were transferred. I am aware of a work-around that people have been using ( http://www.shloemi.com/2012/04/import-blogger-to-wordpress-3-3-x/ ), but the site is already live with new posts and comments so I don't want to risk introducing duplicate posts for everything that was already imported.
Any suggestion on how this can be addressed? The # 50 leads me to believe an unhandled error was thrown near the end of the first comment loop (~line 517 of blogger-importer.php in v0.4) since the max limit is set to 50.
