I was using a friends laptop and went from circle to electrum wallet created on his laptop then sent half 160 to alphabay and rest to nucleus. Neither deposits showed up. I accidentally closed out of electrum right after trnasfering to both markets and neither of my market wallets showed a balance. I got [error 183] cannot create a file when that file already exists when trying to recover the wallet as it didn't open up right away when I clicked on it again, it wanted me to recover for some reason and reset password then I got the error. Why couldn't i just log in with my old pass? Wtf help
Have you tried contacting AB/Nuke support? If the coins were withdrawn from the electrum wallet and the 'withdraw to' BTC addy was correct, then the coins could still possibly be en route to your buyers account(s). Sometimes there's delays within the blockchain. Sometimes the MP's internal tumblers take a little longer. Or if you used an old deposit address, then you're gonna want to get ahold of support so maybe they can track them down before they get sent to a wallet addy older than a week(in which case the coins are lost forever) because the sites don't allow reusing of deposit addresses for OPSEC reasons.
