I have had this dang problem since Before Classic. This is a Constant issue, with addons, with no addons, with only wow Running, and etc. Fix this
It takes me FOREVER TO LOT MY AUCTION HOUSE SALE, AND I MEAN FOREVER. Every Single thing collected from the Mailbox gets the Internal Database Error when opening all mail, it lags the entire game out, and just takes a massively absorbant amount of time just to loot 1 AH Delivery and then Wont Even Show what i Looted from that mail until i have Stopped the Open All and type /reload.
This has Gone on Long enough, it’s an issue that has gone on for almost the entire lifetime of Classic.
