Puzzled and sorry 

I am sorry about the rollback of your edit, but I am totally bewildered about it. I have no idea what happened, but I have to chalk it up to a disturbance in the force. At the time of that rollback, I was feeling frustrated by the fact that I had gotten an error message when I submitted an edit to Wikipedia:Did_you_know/Statistics  and that my edit was nowhere to be found when I hit the back button in the browser. Finally, the page appeared, showing my edit (after I had recreated my edit in order to resubmit it). The rollback apparently occurred between the time I submitted the edit and the time I stopped seeing error messages. I think the rollback (on a page I wasn't even looking at) was somehow to the Wikipedia gremlins I was fighting.

I'm very glad you were watching!
