Auto Threshold payouts - is there an issue?

I see we've been mining FTC (more or less constantly) for the past 7 hours - about 01:08 GMT to 07:58 GMT. So during that time my auto payout threshold has been triggered 3 times, but none of those have shown up in my FTC wallet (yet).  Usually they show within 5 min or so for FTC.

Is anyone else experiencing similar behaviour?
