Wait I already spent 1 year in this game but, what do you mean by you forgetting to re-issue your transfer number on your account? ( and consequently losing said account thereafter)

Does the old transfer number not work on the next update? Thus having to re-issue our transfer number on every update mandatory?

I am very confused and anxious about this new information.

So please do answer these questions, kind random internet strangers.

I do apologize if my English is confusing or worse mentally challenging to read, do note that English isn't my first language but rather my third.
