What's the issue? Please include any error messages you receive and as much detail as possible.
I keep getting this message but this is the first time I managed to not click away from it before it registered in my slow brain.

"Your lioness, Cub, has been flirted with by some inappropriate brute! You have 15 minutes to show them who's BOSS!"

I have no lioness named "Cub" and received this message prior to having any cubs in my lair.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
No particular links.

Any screenshots you can provide us with?

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 can't replicate it since it requires someone else to flirt with my lionesses and then it only happens once and awhile.
