About a month ago Alex King discovered an “undocumented feature”1 in WordPress 2.6 that affects plugins like Cricket Moods. The bug causes post metadata to be duplicated due to the addition of post revisions. Basically, with every new revision you’ll get a duplicate set of moods.
I have hopefully fixed the issue in the 3.x branch of Cricket Moods. I haven’t tagged a new 3.7 release of Cricket Moods because, frankly, I don’t know if these changes break anything. I tested the changes on one Blog running WordPress 2.6. So, before I tag and zip up a release, it’d be great if some folk2 could test the new plugin. Grab the file from the Subversion repository.
To fix any old duplicated moods, remove all moods from the affected post, save the post, add the moods again, and save the post.
