The mood system I guess?

What's the issue? Please include any error messages you receive and as much detail as possible.
One of my lionesses had her personality just vanish today, for whatever reason. I don't recall what it was previously, unfortunately. I also checked all my other lionesses to make sure she's the only one.

I sent a modbox report about this before a helpful person in the chatbox recommended I should post here instead, sorry about that!

I just went to her page and saw her personality was gone, that's all.
