So, there's no option to get back them?
Because when I started again last week after two years I had all my credits and I didn't do the tutorial. I only lost them when I changed this first team for another. Then, I lost all of them and I should do again the tutorial, but not the first time.
This is why I think it's not correct, because if they are connected yo an user, they should came with me to my new team.
