I bought a pet mount retraining card today and tried to send it to a friend but it didn't go through. So I thought I'd try to close the item mall and reopen it and now the gift is gone. And my friend still hasn't received it. I checked the Item Mall's Records and it doesn't show it was sent either, nor does it show that I bought it.
I couldn't remember the time exactly as something like this has happened to me before but when the recipient logged out and back in a few hours after I bought it, they received it. That isn't the case this time though.
I don't know if you can check logs or something but here's the info:
Gift: Pet Mount Retraining Card
Time: 3-4pm EST (-5 GMT)
Server: Katar 6
If you need more info let me know.
