Bugs Thread

[drclavel]

Please anyone, help me.. I'm getting kinda frustrated. Here's the thing.
I've been playing for a while now and I got stuck. I have all the map revealed, followed the main tasks as they appeared. Now I'm stuck at getting Vikings and Elves on my side. My journal tells me to find out why orcs fight Vikings on the last island. I have talked to the Viking-governor but he told me nothing substantial. I have fought ALL the enemies I could find there. I did all the side tasks (apart from killing the black unicorn, which must be bugged, cos in fact I did kill it, but my game won't ackowledge it...). And I'm stuck. There's just nothing else I can do. Queen Amelie is nowhere to be found too. What do I do? Is it a bug? How do I fix it? I can't complete the game.
If my explanation isn't clear enough I can post my saves here - I don't want anybody to do things for me, just diagnose this...
