So a while ago, when the Raven set and Enchanter set were in the cash shop, I added a couple of the items into my cart, and eventually forgot about it. I just went to my cart by accident and they were still there, even though the sets are not in the cash shop anymore. I figured if I tried to check out I would get an error, but I did not and the items are now in my inventory (Also going to file a ticket).

I made a ticket a while ago and they responded and said they'd get back to me but it's been about 5-6 days and still no final response :c

The items were taken from my account and I was reimbursed, but I haven't heard anything about a bug fix.
