Not a Bug PIN Reset, without receiving verification email to complete it.

Description of the bug: (optional screenshot/video): I briefly forgotten my PIN when returning to ML. So I went to the Account Recovery section to reset my PIN. The system was supposed to send me a verification email. During that same period, I suddenly remembered my PIN and logged in. However, after that all logins required no PIN and the system didn't send me a verification email to complete the reset.
What is supposed to happen?: I was supposed to receive an email to complete the reset. However the game reset my PIN immediately without the verification, not sure it's because I logged in during the reset progress. Still, no verification email, also checked the spam/junk folder.
Where did you find and/or notice this bug?: On the ML Website account page (Logging In)
A step-by-step guide to re-producing this bug (optional): Login on ML Website, Reset PIN, enter birth date and yada yada. Website says the verification email was sent; didn't receive it. Logged into ML, and the PIN reset itself without completing the email verification.
Extra information (optional):I also need help from a staff since I am not sure how to re-activate the PIN.
