Now, on to the details of this bug:
This is the first time I have made it this far in the game. I was mid 40's with a Yeek summoner. I entered the Unremarkable Cave, and I am wearing 'The Inner Eye' headgear, which makes me blind and gives me telepathy. Fillarel thanked me for saving her and told me o go see Aeryn, while some orc in the same area said, "Thanks for helping me kill the elf wench." Both were neutral, and that was that. I moved on, slightly puzzled, but figuring things would work themselves out later. MUCH later, I found out that I had missed an important quest here.
So, I got to the city and they wouldn't let me in, so I teleported inside and found some quest givers and continued to play a couple more weeks worth of ToME, after which I couldn't progress any further. After much research, I found out that this quest should have happened but never did. I went back to the cave, summoned a creature, intent on killing Fillarel to see if it would trigger something. I assumed control of the minotaur I summoned and initiated a conversation with her, which was different than my first one. This time, I selected 'Kill Krogar' and the orc went hostile.
Of course, my summoned minotaur could see, so maybe that had something to do with it. One more thing: There may have been a LUA error here the first time, but I can't remember for sure. A LUA error that I didn't report did happen once but wasn't logged in online. I couldn't get a bug posted because it disappeared when I tried clicking to copy the text.
Hope that helps!
