Is your feature request related to a problem? Please describe.
It seems these lines is not used anymore, i can't find a way to make it output to console or client.

error.not_logged_in: '&cYou''re not logged in!'

misc.account_owned_self: 'You own %count accounts:'

Describe the solution you'd like
I just want to know how to make it output, for translating it to my language for player to be better understanding specific situation.

Describe alternatives you've considered
Delete it if it does not exist in the newest version, i tested this on 5.6.0. I used to use 5.4.0 version and it DOES have the output but not on 5.6.0

Additional context
no
