Hi there,
after the initial tests of the recent update I wanted to do the tests again.
For luck I stopped playing in my 2nd world at vesslan bunker, so it was fast and easy to do everything again to unlock the companion.
This was the moment where I got the idea to become able to copy one existing world on a slot of another world.
Just in case something brakes, you would easily be able to restore an earlier state of your world, for example after each update.
What do you think?
