Fortune Bag Refund Glitch

Hello I am Kaboto from Pazuzu(1566). I went to open a 10x Mount Fortune Bag and I got somewhat lucky, I got a mount skin I already had and clicked on the square that refunds you if you have the copy already. Then, I got another copy that I already had followed by Lunar Wolf Soul + Mechanical Bison Soul but the game said I already had these mounts, which I didn't and the game refunded me my 33 coins per mount. I am simply letting others know they should NOT press the square at the bottom for refunding because it will auto steal any mount you get in you x10 pull, regardless if you don't have the mount or not. Stay safe, Kaboto
