I completed the third guard post and went to speak again to Captain Cormak, could not enter the city watch 'cause I seemed to have a graphic problem (first time that has ever happened after playing several NWN and NWN2 games)

So I saved, tried to load but could not, gave me an error. Restarted the computer and started again from my previous save, but now I only see 2 guard posts marked on my map. The third has the sergeant and the other city watchers either half dead or injured, meaning, the fight in the third guard post has happened. But nothing happens anymore. I tried to talk to that butthead Cormak again and he tells me to take care of Hagen.

Any ideas?

the journal tells me I only have completed 2 guard posts, but the third is like won't trigger. What a bummer
