I just found an old wallet on a recovered crashed drive from 2012 with almost 20BTC worth of unconfirmed satoshidice transactions. I looked them up in blockchain and there's no record of them having occurred, with the client's blockchain fully updated. I remember having a similar issue a long time ago and It resulted in me recovering the funds but I can't remember if the specifics are the same or how it was done. What can I do about this issue? (EDIT: I believe it was done with pywallet but I have no idea if it's even still being maintained)

I'm still in disbelief. If this is real I'm going to be so fucking happy.
