What's the issue? Please include any error messages you receive and as much detail as possible.
I'm a mass NCL breeder, but it's a pain when on their last day of pregnancy they are at the risk of leaving the next day when they give birth and the proper symbol doesn't show up. I just want the lightning symbol by their name like any other lion/ess to give me some kind of warning so I don't lose all of those potential kiddos the next day.

Any links relating to this bug? For example, if a particular lion is bugging, what is the link to that lion?
No, because all of the NCLs affected ran away from my pride.

Any screenshots you can provide us with?
No.

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:
The lightning symbol that signifies a lion/ess will leave at next rollover does not apply to NCLs. It's frustrating for NCL breeders because we get no alert, and needs to be fixed.
