Ok so what happened is I *sent* the transaction, at least the electrum walled show it as sent, but it was never actually sent / broadcast on chain.
I am not sure how the electrum wallet thinks this transaction has happened.
I probally have to reload the headers or something.
To get the right wallet I restored a wallet from the *zpub....* again.

That sometimes happen if the server you're connected to somehow dropped it from their mempool,
or since you're using a cold-storage set-up, you may have clicked "save" instead of broadcast after loading the signed transaction.
Either way, it will be saved as a 'local transaction', indicated by the 'blue computer' icon instead of the 'check', 'pie' or 'clock' icon.
