When I checked my player mail in-game after logging in for the first time today, I had hireling mail (system mail) and gold proceeds from a guild store sale (~13k gold). I collected all of my hiring mail using the new feature to "Take All". I also have the "Delete After Claim" option checked. Both of these options worked fine for the system mail. Then I tried to claim the gold I earned from the guild sale. Prior to collecting the guild sale I noticed that the gold balance in my character inventory was ~114k gold. The guild sale item proceeds were ~13k gold. When I attempted to claim the gold, it was as if nothing was claimed (didn't see my balance change and didn't hear the sound of coins "clinking"), then the mail was deleted instantly.

I believe I noticed this happening yesterday (June 12th) as well when I first use "Take All" for my hireling mail and then try to claim my gold proceeds from guild sales in the same mail session. However yesterday I wasn't paying attention to my gold balance before and after. I thought it odd that I didn't hear the usual sound of coins clinking when I claim the gold attachments so I thought I was imagining things. I was able to claim new gold attachments later in the day when reopening my mail in another session where there was no other system mail in my inbox. I think there is a bug with the new mail updates when you collect system mail attachments AND try to collect guild sales gold in the same mail window. It's probably wishful thinking to try and get back the mail with the $13k gold that I was unable to claim today, but I would like to know if someone could look into this bug. I opened a ticket (#240613-001566). Thanks.
