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:
I searched for web/cobweb group marks, found her and bought her, I am not sure of the following steps after, just that when I keep searching she is the only one that still sits there, despite buying other lionesses/trades
