Lion

What's the issue? Please include any error messages you receive and as much detail as possible.
I had a lion listed for a raffle, which was canceled. The lion is now 'stuck' in a nonexistent raffle, so I can't sell him, abandon him, etc. I waited for rollover to see if it would fix the issue, but it did not.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?

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:
Raffle was canceled on 1/3 automatically (not enough tickets sold). Lion still "being offered as a prize in a raffle". Clicking the link leads to a page stating the raffle has been canceled. Any attempts to chase/kill/abandon lion elicits error message stating the lion is currently a raffle prize.
