What gameplay feature is this bug affecting?
Studding and Reverse Breeding

What's the issue? Please include any error messages you receive and as much detail as possible.
Despite having a leopard tail in my hoard, not buried, I can’t send it to be used by a stud or by another player’s lioness for reverse breeding. Unlike every other breeding object in the game, it does not show up as an option when sending stud or reverse breeding requests.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
No particular links, it doesn’t show up for any stud I’ve tried.

Any screenshots you can provide us with?
I can screenshot the stud page and my inventory, but I’m not sure how to attach screenshots in the forums.

Please provide us with step by step explanation how this bug happened so we can attempt to replicate it. If it's complex, please include screenshots where possible:
1. Go to a lion’s stud section or a lioness’s reverse breeding section
2. Check that you have a leopard tail in your inventory
3. See that the leopard tail is not an option under send breeding items
