So I guess the new question then is: how do you recover a transaction that was sent in March of 2014 to an address on a wallet that holds the rest of the transactions to that address if the blockchain isn't syncing it up with the wallet even with Bitcoin Core fully downloaded/synced?
It still sounds (a bit) like a synchronization problem.
showing as sent / unspent to the same address as the 3.5 and 0.4BTC
It's on a different address, right?
Also, is anything (other than a private key/encryption phrase of course) not safe to show as a screenshot?
Any address will (slightly) compromise your privacy. Be careful what you enter in console though.
If you're holding 4
BTC in a hot wallet, you should probably improve on that! It's now worth a small fortune or at least a very nice car. Cold storage is the way to go (but don't do this unless you're absolutely certain you know what you're doing).
And
after you've moved your Bitcoins out of your current wallet, don't forget you hold (at current value) about $2500 worth of
Forkcoins. But don't bother touching them before moving your Bitcoins to a new wallet (you don't want to risk them).
