When keys are imported and claimed, their ownership goes to a new address which is derived from the wallet key (as I understand). So can those private keys be re-generated deterministically from the wallet key? Or after every address import do we have to make a new backup?
Thats what these docs seem to imply:
After importing your accounts and balances, we recommend to make a new backup of your wallet that will then contain access to your newly imported accounts and corresponding balances.
If thats the case then the docs should be more explicit. I wonder if this is where I messed up...
