There appears to be a fork in the network, some nodes are reporting block numbers at 17723, others are reporting 17735.
Explorer is stuck at 16299, so it likely never got updated.
This is what I get for block 17722:
litecoindarkd getblockhash 17722
c199d4c2c07d231d0e46323b763272ca94c0e13f4af069d7b704c72f579e143f
I get f9c01ca419d1336c4bc4c6481a2f9a7751b2c9de2b0fce2756a438a5d7b389a8 and my wallet is on the same chain as Best-pool and Bittrex.
Looking at number of trades at Bittrex since the fork, this coin will be finished if Hashlink will be able to dominate the chain and Bittrex will need to cancel trades/deposits/withdrawals, etc.
