“Got Lost” as in you no longer have that email address anymore ? (changed service provides, was a school account, etc ?)

Or that you don’t remember what email it was that you used for that account . (can check SETTINGS page in game, Login page, it will tell you who you are currently logged in as).

But I assume the prior, as if since you have multiple accounts, and are switching between them, you likely are entering that “Lost” email as username as part of switching logins between your game accounts.

As well as then the “Submit a Request” link within there, but you will need to know answers to questions to verify you know it is really your account.
