Drops for a many main keywords while others are still r

Today a ton of my keywords dropped while others have been completely stable or rising. No manual penalty or anything. One keyword in particular has been ranking position 10-15 for 2-3 weeks is now 41 for example.

Recent changes I've done :
-interlinked 5-10 posts to other pages on my site
-removed Hentry from posts to reduce errors (supposed to have a positive effect)

All links seem to be live as before. No major changes done to the site and no thin content on it.

Any ideas what might have happened? Is Google just recalculating?

Google did an update today.

Wait few day, see if it go back.

It seems like Google dance. Just wait for few more days, it will settle down at a good position.

Any changes to your website may cause temporary fluctuations in your rankings.
