I unfortunately had to manually move my photo folder rather than doing it from withing Lightroom. The result was that my keywords became messed up. Somehow, all the photos that have stars (my good photos) have had all the keywords moved into a strange sub-folder under the keywords Personal\Events. This didn't happen to my unstarred photos. Have a look at the two images to see what I'm talking about. With a catalog of over 100k images, I really don't relish going in to re-enter my keywords. Does anyone have any ideas for how this could be fixed?
