Comment indexer shows deleted comments

I created a comment on a blog to test the email functionality then went in and 'trashed' that comment but it's still showing up in the recent comments plugin. Since that's pulling its feed from the comment indexer, I assume the indexer isn't rebuilding itself or checking to see the state of a comment? My version of the indexer is 1.0.2 right now. Is this fixed in a newer version?

If I install a newer version is it going to lose previous indexing or rebuild it?
