I watch a number of different tags at the same time using the tag filters and I noticed that today, the sort order of the newest tab seems to have an issue.
Towards the bottom of the first page, I have questions from May 2011 and Dec 2011. There seems to be questions missing/skipped in the sorted list.
When I check the old questions listed, I can see no recent updates that would have pushed it to the top. Even so, newest sort order used to be ordered by the question posted date, not active date.
See https://stackoverflow.com/questions/tagged/drupal+or+drupal-7+or+ubercart+or+struts2?sort=newest&pagesize=30 for example.
Is this bug? How can I restore the correct sort order as it was before?
EDIT: Just checked again and now it's fixed. I wonder, what was the problem?
