Re: Account merged with daughters.
Hey @tigerfursonly,
This would happen if you both had separate platforms connected to the same EA account when Cross Progression took place.
You would need to have your platforms linked to separate EA accounts to be able to play simultaneously.
Progress is stored on the EA account level, not on individual platforms like PlayStation, Xbox, Steam, etc. This means if you link your platform to a different EA account, you'll lose access to that progress.
Unfortunately, whichever account is unlinked from this EA account will lose access to the progress here as a result and would be starting from scratch on the new account.
Please feel free to check the FAQ below as it has a bit more information on this exact scenario, thanks.
