Hey Doc, is there something wrong with the payouts? Should have gotten mine since the last BTC block, but nothing shows up in my wallet?!

Is your balance above your cash out threshold?
Is the auto cash out turned on? Leftmost column in the auto cash out settings.
Yes to both. I've even checked if I my wallet can receive payments at all at the moment and yes it can.
My balance went to 0 before the last block and so I'd expect a payout, but it didn't happen

If your balance went to 0 then there was a cash out. It won't show in your wallet if your wallet is not synced with the bitcoin network. It has to download all the blocks. While you let it sit and download blocks you can look up your address at blockchain.info and you'll see the payment there.
