It is sold by Lorelae Wintersong in Moonglade.
She had it in her inventory, available to purchase. I bought it, my money decreased, however, the icon in her inventory completely disappeared and it was never placed into my bags.
this is normal for limited stock items.
did you use the bag search option?
if youāve got bags assigned to crafting, it would go into that bag instead of your backpack.
I meanā¦it disappeared like it bugged out. Glitches out. For a minute, it was stuck at (1) item available. I clicked it, it made the noise as if I purchased it.
The 1 didnāt go to zeroā¦so I thought I didnāt buy it. Spent a good minute ābuyingā the pattern, and each time I clicked it, it made the loose change sound. Eventually the entire spot went blank, and I never got the pattern.
Checked my bags. They were all empty except for my hearthstone.
