UPDATE: Bitcoins are back in my Electrum wallet and transaction has disappeared. All is well.
I transferred the content of my Electrum wallet to my Alphabay wallet, but turned off Tails before any blocks had been mined in the blockchain. When I logged back on, my Alphabay balance has remained unchanged and Electrum lists my balance as '0.2254 [-0.2254 unconfirmed]', and the transaction is listed as having an 'Unconfirmed' date. I have attempted to view the transaction on the blockchain, but it states 'Transaction not found'. Where have my bitcoins gone? I know it might seem like a trivial amount, but its quite important to me right now. Any help would be much appreciated. EDIT: I figured it'd come through after a number of blocks, so I just waited ~20 hours, completely re-installed Tails, restored my wallet, and nothing changed.
You just have to wait. Make sure your electrum is connected and wait
