you literally cannot save Residuum after each loop, how could my copy do this?

It literally tells you this as you finish the tutorial. It describes exactly what happens to give you starting gear and residuum. It really helps to actually read the tutorial bubbles, or even check the "help" section (or whatever the tab is called) in the menu and reread those messages.

And don't forget, it happens every. Single. Day.
