I gained 20 reputation on two events but why am I not able to see it in the Reputation Tab?
Is it some fault or feature of SO? Note: I have refreshed my page thrice but nothing seems to happen.
It takes sometime to update the Reputation tab. Probably your Reputations are update first and then Reputation Tab. Many a times I too see that happening. My reputations are increased/decreased but the Reputation Tab is still not updated.
