if you have a wallet backup it's easy to get them back again.
Just delete the current wallet with the lost coins, and put the intact backup in place.
Then run gridcoin and it will rescan the wallet and adjust for all transactions that did and did not complete.
I've been having a bunch of transactions not complete and get them back this way.
Also, I had some that remained uncompleted for the better part of a day suddenly go through. I believe it had something to do with the timing of finding a new block. They sent right around then. So it might have taken them that long to notice they had a node to travel to and confirm on.
edit: typo fix. them/then
I transferred the last days some coins to my back-up wallet cos my wallet size is exploding (6Mb), all transactions succeeded, except the last one from yesterday.
Money is not in my wallet anymore and in the transactions historie I can see following,
19-1-2014 12:00 To FyxhBbEjhfWQznDHjrJWpCgcz8WuiXuq8E, debit -500, transaction fee -1,74, transaction ID 7b55bba6ad2c75a4c1211c7fc33ad891012579effe421093dfdd2d9152561d6b
However Status 0/unconfirmed.
After that transaction I got three mined received transactions, they are all confirmed en show up in my balance.
Upgraded just to 1.1.5.7-g71-prod/70
What can be wrong, are these coins lost??
