When I filter questions for example by https://stackoverflow.com/questions/tagged/entity* and select the "newest" question tab and 50 questions per page right now the last question on the first page is "asked Mar 6 at 23:11". (Today is March 14 and the bunch of tags selected with the wildcard isn't that inactive normally.)
Selecting only one of all those tags (which should just be a subset of the wildcard url) by https://stackoverflow.com/questions/tagged/entity-framework the last question on the page is "asked yesterday".
Is there a problem with the wildcard search or some other bug? Until yesterday it worked as expected for me.
It might be a sorting problem. The number of pages looks correct. However, at the moment page 3 for example ends with a question "asked Jul 20 '11" ...
...while page 4 starts with a question "asked 19 hours ago":
Another example: On this page 6...
...hundreds of questions about ASP.NET MVC are missing (or the "newest" sort order is somehow different than it used to be):
No new questions about ASP.NET MVC(*) for 11 days?
