the last block was "orphaned" see
https://en.bitcoin.it/wiki/Block_chain for an explanation
it has since been credited to depbit.
I spent an hour chasing around working out what happened, sorry i cant post before i know an answer. For more "uptodate" or "realtime" news members are welcome to click the "web irc " link on the site and join irc.
as for transparency, i have screenshotted the wallet and

hopefully to help in having to explain to all the miners that havent heard of or understand an orphan block.
Ozcoin pays valid block to valid block, so yes the shares from the orphan block were added back to the stats to be sure that every share hashed on Ozcoin is paid out. We are still a fairly young pool and cannot afford to pay for "invalid" blocks (like some pools can), we do not feel comfortable just "dropping shares" from invalid blocks (like some pools do), so we feel this is the best and fairest solution.
Hope that is a help.
I will post the screenshots in Ozcoins forum in the morning << sorry its afternoon, Post is up in the ozco.in site forums
