I just noticed that when I opened a mail from a guild store sale, the gold amount was not added to my balance, but the mail was gone. I am on PS5 and used the X button as indicated to collect the gold. But it didn't work. I am honestly not sure if this happened with any of the sales I made during the past few day too. This is disturbing as I have been selling a lot of gold upgrade materials. This instance was 33.480 gold. I have save a screen recording of this, so I will also make ticket for it. But I want to warn other to make sure you check your gold balance before collecting the mail and afterwards to make sure you received the gold.
