For players who experienced an issue getting the proper amount of storage when purchasing an Underdark Patron's Coffer, we have identified the issue and we are working on a fix that will be deployed in a future game update. No ticket to Customer Support is necessary to correct this issue, as the fix will be a versioning fix that will be automatic once the correction is deployed.
The Dark Fire Glamered Weapon Aura of Underdark Patron's Coffers is bugged.
When adding a Glamered Weapon Aura to unique weapons like Lacerator and Enduring Conviction for cosmetic purposes, only the blade shines, and the aura is not displayed.
Not only the Dark Fire Glamered Weapon Aura but all Glamered Weapon Auras are bugged.
By the way, there is a bug that prevents adding a Glamered Weapon Aura to the Legendary Sword of Shadow as well.
Please imagine the sadness of paying money and not having the Weapon Aura displayed.
I was really disappointed when I wasted money on buying Mirrors and couldn't add the Shadow Aura to the Legendary SoS.
I hope it gets fixed soon.
