I stumbled upon some odd behavior that looks like an intermittent bug to me.
On two separate occasions (only a few minutes apart, but it was working fine in the meantime), once on page 15 and once on page 16 of the bounty questions, I got the message
There are no questions with an active bounty at the moment.
Needless to say, that was not the case.
I took a screenshot when it happened first:
Direct link to the site: stackoverflow.com/questions?page=15&sort=featured&pagesize=15
It is working fine right now.
Every time it happens, it seems to affect all pages from the 15th to the last, but only those.
The reviews page seems to be affected by the same bug: No new users made their first post today?
