Sylvian camp map 1: bug?

[Bethel]

This is Freelance, Bethel's son. I've been trying to get through Findan's first map, the one with the garissons. The first time I played through, the demons showed up. since I spent my army on filling up the garissons, I had none to fight her when she broke through.
so I changed tactics and been holding onto my army. Of course, no she's not appearing at all! The only thing I can think of is that since teal has cut through the garissons, the timing has been thrown off-kilter, and the timed event is missed. I'm now in month EIGHT, and still Biara's a no-show. Anybody else having this problem or know the solution to what's going on? Thanks in advance for any help you can give.

I had that problem too. I had to restart, and then it worked fine.

I did too. It's still not happening.
