Maria can work at the bar you just have to progress her story up to that point, so until you have her story there, Moon's story will be stuck where it is
I'm well aware. I've gone well past that but after a certain point i.e when she learns to fight, she no longer works at the bar. Thanks but that's not what I was asking.
You are right, I have the same problem. Stuck at Moon lvl 4 and can't get through it, because Maria no longer works in bar. It's the only thing I can't complete.
