I was trading recently, and I put up a Felis Male for 3000 SB or 3 GB. Previously I had only done 2 other trades, one lion for 100 and one lion for 150. I didn't check the 150 lion, but the 100 lion I didn't get any money for, as it cost me 100 to put up for trade. I just thought that maybe that was the base cost for making trades, so I didn't bother with it, but when I put up the Felis for 3000 SB, it cost me 3000 SB and I didn't realize it until it was bought, and I didn't make any "money". I don't know if this is just how trading works or if there is a bug or something but anything you guys know would be greatly appreciated!
