This question ( Consecutive Days bug/glitch ) is exactly the same problem I've had. I logged on yesterday and I have a screenshot to prove that I DID in fact, have activity yesterday. But today all my SE accounts (I have been clocking up a few at the same time - Stack Overflow, Code Review, Christianity, etc.) have been reset, and I was on 50+ days for some of them.
I have two questions:
Was there an outage as described in Rob's question yesterday? I logged in around 10:00 AM as I do everyday (South African time is UTC + 2 hours), so this isn't a case of me hopping between time zones.
How do I fix this for all 7 of my stack exchange accounts?
