So I was selling an item at Jita in bulk. The situation was roughly like this:
$2000 | Quantity: 3 | Neat Item <- My sell order
$4000 | Quantity: 1 | Neat Item <- Someone else’s sell order
$4250 | Quantity: 1 | Neat Item <- Someone else’s sell order
I got a notification that my sell order of Neat Item had gone from 4 to 3. When I looked at my transactions, I saw that the order had gone through for $4250 even though that was not my sell order.
If it matters, of the three sell orders listed, mine was issued before the other two.
What could have happened here?
