I was adding an answer to this question, and the banner popped up saying "1 new answers as been posted - load new answers". When clicking the link, nothing loaded and the banner disappeared.
A few seconds later, the banner reappeared. This kept happening and I clicked a few times but no answer ever loaded. After I submitted my answer there was no additional answer, just the one already before I started mine.
Perhaps someone posted an answer and promptly deleted it before I clicked "load new answers", but the banner should not keep appearing unless there is still a new answer.
