Den Item Tag Glitch

Sometimes den items on trade appear with the tags of another clothing/pet item on trade. This glitch doesn't happen if you only have den items on trade. Instead, the bugged den item glitch occurs.

If the item the glitched den items took the tags from a pet, you are able to click the adoption certificate on the glitched den items. The certificate will just appear the same as the pet it got the tags from, to the right of the glitched den items.

If you switch rooms and open your trade list again, the glitch will be fixed. This glitch happens on your own trade list only. While you are glitched, you can't trade/gift/sell/recycle den items or put more on trade until you fix it. However, it's possible to remove the glitched den items from your trade list.
