Look there. It shows that my reputation on Stack Overflow is 1,553. Actually, it is 2,081.
Now look at April 20. It shows that my rep on SO was 259, and my rep on MSE was 129. Wrong, again. That day it was 730 on SO and 101 on MSE - I have just registered on MSE.
Then look at May, 15. It shows 1,323 on SO and 174 on MSE. Actually, I had 1860 rep on SO and, well 167 on MSE, almost right. Now it shows right rep for MSE and completely wrong for SO and shows negative rep for a period since April 10 to April 16 .
