Hey

I'm confused? That's not your forum account.

So explain the "bug" or issue that your friend is having.
His exp matches his rank from what I'm seeing.

Ninja School Trainee is correct.

There's no missing R and Trainee has two E's.

This isn't a bug. Additionally, Explain issues in the text, sometimes a "title" doesn't say that whole story.
If you have any issues with this answer, or you have any more questions

Feel free to message me.
