I cannot find a way to trigger it. I think she is lvl 13 at the moment and the only 2 stories to complete are Kali and Android but I am completely stuck and cannot find a way to proceed. I am thinking I got bugged. Also I never used cheat codes
I have played through the game multiple times without any issue and last time I made a thorough set of notes including what all the characters' events are. Kali's 14th is activated simply by knocking on her door, please try different times of day although this early on I don't recall time of day being a concern. So long as she's not in the shower or in the lobby this should work fine.
