Gold 'dissapeared' from mailbox

Hi there,

I'm having some issues with gold that comes to the mailbox from auctions.
Yesterday I had about 270 of these "sale pending" mails, along with 70 mails not showing because the mailbox was full - At least some of these were probably also sale pending containing gold from my auctions.
This morning when I logged on again to collect it, it was all gone. Out of the 270+ emails with sale pending, there was no gold at all to collect, the mails and the gold completely gone into nowhere.

Has anyone else experienced something similar to this? What's causing it, and how can it be fixed?

I do loads of auctions each day, so I've probably lost a huge chunk of gold due to this if it's a recurring error.

EDIT:
Possibly related to this https://www.warmane.com/bugtracker/report/439 ?
Pretty sure however that I didnt receive the gold from all those mails.

same here...pending and no gold....

This is a very common thing which the staff keeps claiming as false. So good luck with it ever getting fixed.
