Whenever I sell a pet, the transaction says "You sold *pet* to *username in orange colour* for *money*". But the other person's username is un-clickable.

All the orange usernames or pet names listed in the report section are clickable in any other setting(such as for example when you recieve money for a breeding offer). But not for "pet trades" where you've sold a pet.

Perhaps it's a bug that causes the other person's username to stay un-clickable when you check the report section for pet trades?

Thanks for reporting!

The bug is fixed. The fix will be visible only for the new entries, the old ones will stay as they are.

Sorry for the inconvenience.
