If the tx don't exist in blockchain, the coins didn't get sent and are not lost. If they are unconfirmed you could just delete these tx (if using daemon with "deletetransaction ") and rescan.
Hi wiggi, thanks for the suggestion. I tried it on the first TxID using:
~/huntercoind deletetransaction 4ec87119207535c35943473aec9bee2a81fd278d07b65e5bb72c6f59cde6bf5e
but got this error:
error: {"code":-1,"message":"transaction is already in blockchain"}
So it seems the transactions are in the blockchain, but none of them show up in the explorer - very strange no?
You can delete any tx from a wallet (even the actually confirmed transactions) if the wallet is rescanned with an almost empty blockchain (e.g. with only a few hundred blocks). This only takes a few seconds, then all tx appear as unconfirmed.
Not sure about the rescan error, probably best to delete this blockchain and start over with the downloaded one if you still have a copy.
I'm confused - why would the wallet report that the Tx was in the blockchain if it wasn't?
I no longer have the chain download & chain.huntercoin.org leads me to a server welcome page - has that gone now also?
If anyone can post a link to the huntercoin blockchain download I'd very much appreciate it.
Thanks.
OK - following up on this issue, I finally downloaded a new blockchain & compiled the QT wallet as advised so that I could actually see what was going on with my missing payments. After rescanning using the original walletDAT file all 15 payments show in the wallet:

I'm not sure if this is a bug in the blockchain, a bug in the client or a problem with the Poloniex wallet (although they seem sure that it isn't) - so I'm completely open to suggestions or ideas on how I can fix this - no matter how weird or wonderful....
Thanks all.
found them and made a new wallet. My problem is i lost them 1 second they were there, next after i closed and reopened qt they were gone, here is a link to what he suggested to me, might help 
On rare occasions, though, I've seen GUI glitches like that which go away if you restart the client. If that were the case, then you would not have managed to move your Hunters from their spawn locations in time, causing them to despawn, which will eventually give you your HUC back.
