Anyone else having this 'disappearing' BitcoinCash issue with BitcoinABC wallet? Today I was in claim BitcoinCash mode, which I completed successfully with my Ledger Nano S and also with my Trezor. Then it was time to for the Bitcoins I held only in my Electrum wallet. I retrieved the private keys and set out to import one into a new BitcoinCash wallet. All bitcoins were first moved off Electrum to a different wallet on a different computer. I then installed the BitcoinABC.org wallet. When that was done I encrypted it immediately. I then used importprivkey to import a private Bitcoin key that had previously held .1 bitcoin.

The blockchain scan started. I let it run and went to lunch. When I got back, the .1 bitcoin cash had been received, but there was also a send transaction 39 minutes later to a BCC address (36uzTBVeWN2pvUu3YX22gCutovGwQg1eeS) I don't know. I didn't make the send transaction and there are no other people that could have and no computer issues, malware or otherwise on my end. Also, I had a list of other private keys open on the same computer and only issue is with the one key I imported to BitcoinABC wallet.

How was BCC sent from my encrypted wallet, where only I (and BitcoinABC wallet after importing) have the private key, if there isn't a vulnerability in the BitcoinABC wallet? 

Has anyone else had this issue with BitcoinABC wallet? 

Is there a BitcoinABC wallet rep on this site that can address this issue?
That send is from before the fork on 3/31/2017. That means that you sent Bitcoin on 3/31/2017 to 36uzTBVeWN2pvUu3YX22gCutovGwQg1eeS, and because Bitcoin Cash shares the same history as Bitcoin, you will see this send in your wallet.
