the obvious reason would be the sites removing your link / google might have deindexed those directories. you must check by entering those pages to see what is happening to those sites.
I see your site is still indexed, does your traffic affected too? If not then I think there's nothing more to worry, maybe you can check your backlinks if your link still exist. Then just continue getting more links to keep your site indexed more often...
