The number of featured questions on questions and main page don't match

The number of featured questions on the questions and the main page don't match: 63 vs. 64

questions: main

Why was that?

I don't think that my standing bounty is counted as well...

• @ArthurFischer yes, I edited. As for my "standing bounty", the revisions show that I actually added a bounty. In the optional text I promised another +100 and after the bounty period I added a note to the body, where I promised +150. This I raised to +200. Thanks for the hint how to start a bounty but I already spent 1750 of reputation on this feature... – draks ... Dec 8 '13 at 14:09
• @ArthurFischer any idea why they didn't match? – draks ... Dec 8 '13 at 14:23
• Sorry, I apologise. (One time where the revision list would have been much more clear than the timeline, dammit.) At any rate, I have no idea why there was a mismatch at the time. I would expect (hope) that the information is all pulled from the same place and in the same way from the database. Is it at all possible that a new bounty was added in the interval between the the loading of the pages in question? With only the screenshots at hand I cannot even guess at a different cause. – user642796 Dec 8 '13 at 14:50
• @ArthurFischer it is happening again right now: 58 vs 59... – draks ... Dec 8 '13 at 22:32
• Thanks. I was able to catch it myself. Actually, I caught a 60 v. 58 discrepancy. I officially have no clue whatsoever what is causing this. – user642796 Dec 8 '13 at 22:50
• What's more odd is that I found three questions from Main > featured (claiming 60 questions) that weren't in the list from Questions > featured (claiming 58 questions): one, two, three. – user642796 Dec 8 '13 at 22:55
• @ArthurFischer for test reasons a started a bounty, which immediatley popped up on main (screenshot, just note the counters, displayed one is not mine)... – draks ... Dec 8 '13 at 23:58
