Multiple tweets lost!

Some of my most recent tweets just seem to have disappeared from my profile page. I am still able to access them directly.

Here's the complete list:

I was trying to delete a single tweet, but the delete operation never seemed to succeed, so I tried and tried again a few times. Finally when it did succeed, I found that a whole bunch of my tweets were gone!

Note that I was only trying to delete the one tweet; at no point did I accidentally click on any of the above tweets, so I'm not sure how they all got deleted.

I'll be grateful if someone from Twitter can restore the above tweets back to my timeline.
