1. Does not answer the question: Do you have 2FA enabled on that account?
Not providing an answer to that question intentionally. It does not affect or apply to the issue.
Wrong. It applies VERY MUCH to this situation, as if you haven't properly protected your account, it's possible (maybe even likely) that the account was phished or hacked, etc. and that is the cause of this whole issue to begin with....next:
2. Do you have any transaction IDs we can try to look up so we can see what the hell's going on?
Not providing an answer to that question intentionally. Reluctant to expose that data publicly. Blockchain.info might want it before sharing with the world. I'm sharing the problem. It involves the use of their mixer sendy thingamajig to send a smaller transaction. This re-attachment of the original funds seems to be related to sending a small portion through that mixer sendy thing. [sent less than 1BTC through mixer sendy thing, my huge pile of BTC somehow get tangled up and/or bitcoind did a stupid internal send).
First, no one can help you without being able to view the transaction. Second, the transaction has your public key, which you can freely share with anyone. It does not contain your private key, and there's no reason you should really worry about sharing it - especially when it's the only means by which any of us can help you.
Edit: I'm not arguing to be a jerk. I'm arguing because you're in here asking for help, but refuse to provide any information that would allow people to do so. I'm doing this so we *can* help you
