I've never seen anything of the sort since NA launch, so I felt compelled to login and make an internet note. Had a sour day in the labs last week (lost 70+ hours of experimental data to a bad homemade program), and was talking it over in game while doing my full moon crafting. I don't craft at AH or sell on main, but I was at the AH when I made the accident of typing out angry replies while rushing the AH lag buying up gold stacks. You have puchased a Goshenite for 260,000 gil. Not a big loss of 255k, but still a gd thorn in my side. A quick search shows that its clearly a mule that sold me the Goshenite, and having done this several times over the years, I immediately considered the gil as lost.
Anyway, here I am a few weeks later when 255k shows up in my delivery box! I'm a heavy smoker once I get home, so I don't clearly remember if I sent the goshenite back or not, I normally do in these instances, but regardless, kudos to whoever the hell has the mule Moonmist! If anyone knows the guy, pm button prz.
