I very much hope someone is knowledgeable enough to point me to the right direction and help me locate my Bitcoins which are nowhere to be found:
1. Created a "request payment" in Bitcoin Core and used the payment information address to send coins from my localbitcoins.com account.
2. I deleted the "requested payments" entry in the Bitcoin Core wallet before coins were received.
3. Blockchain.info shows the a "total received" and a "final balance" as well as 99 confirmations so I presume the transaction was concluded.
4. My wallet is fully synced. I restarted it numerous times with the -rescan option and compared the block numbers; both in my wallet's debug window and the last one shown in blockchain.info are identical.
5. Support at localbitcoins.com confirms that the transaction has been sent successfully and confirmed on Blockchain.
Yet, after some 48 hours, the coins haven't been received by my Bitcoin Core wallet, i. e. the balance remains at zero and it shows no recent transactions. Any ideas what the problem could be?
