I was browsing on So when I noticed something odd. The "featured" tab that contains all the questions with bountys on them displayed its counter at 0. I tried reloading the page to check if it was just a caching error, but the problem recurred. When I then clicked on the "Questions" tab, the features bar loaded properly.
I tried closing my browser and going back to So and the problem happened again. Its relatively minor bug, but I thought it was worth noting. I've included photos of both the broken counter and working counter.
