Guys. Don't trip. You will get your money. Some of you spend so much time worrying about this stuff, that you forget how you made the money in the first place. You'll get it. The AdSense blog will surely do a post on the situation soon, if it turns out to be a problem. No biggy.
Like they said, it was a visual bug, so it shouldn't affect the data part of things, and you shouldn't lose anything. I would like to see more about this.
The blasted Google is trying to make up for their revenue losses by bilking small time AdSense websites.
It's only when you click on the report for "Since last payment" that you see money missing. There's a bug which does not go all the way back to the date where you last received a payment, that's why you will see your revenue less. However if you go to advanced reports and do it for the previous month and then this month to date, you will see that the revenues match. Update: Bug has been fixed btw.
