Does mylot go wrong?

Tweet

Just an hour ago, I start a discussion with title "Do you care about your mylot reputation and does it bring more paid". About half an hour later, there are three mylotters give responses. And I clicked "add comment", after typing my comment and continued to click "post comment", something strange happened. The two of three responses disappear and my comment is combined to the discussion I started earlier. What`t the matter? Does mylot go wrong? My dear friends, have you ever meet this before?
