There was one rather long (27 blocks) chain that became orphaned 7 hours ago, and two of those blocks were found by our pool.
Did this affect your earnings? Not at all! (It only affected the pool's wallet, d'oh! )
Here is the root of the orphaned chain:

Hello , My Account At litecoinpool org found 2 blocks ,
Why Finding a block does not result in any additional reward?!
A miner's rewards are based on submitted shares, and completely independent of whether they find blocks. This is consistent with the message you quoted. See also the Beginner's Guide and the FAQ.
