It seems some mail got lost when transitioning to TBC. I instantly noticed this when logging in my TBC char. Now I paid 15e to check if the mail is there in Classic Era, and sure, the Classic Era mailbox has more mail in it. The mail messages in question are 30-day return mails from alts. Quite possibly it is the mail that should have returned during the maintenenance that is now lost in the TBC clone. Seems like there were problems with the data migration.
yea i used TBC restore mail for missing bg marks only thing it did was send me a letter from bg without the marks, sended 3 help request but they simply delete the request and do nothing, great service 10/10
It is intended that BG Honor marks were purged during the pre-patch maintenance yesterday. This is to prevent an early start.
