I continued playing after Ossira. :smile52: But I still had to replay the mission - Biara just wouldn't show up(( It would have been very interesting to see who would have moved on to the next scenario...
So maybe you should have waited? :)
And seriously, I didn't have any glitches in this campaign (I'm playing the licensed version, and I've played it twice).
Maybe you should install the patches (you mentioned somewhere that you have version 1.0)?
