I hope it's okay to post here, as I didn't want to create another topic regarding the same issue, and this one is relatively fresh.
I ran into the same problem with Fane's dialogue in Arx as a lot of people had reporter already. Trying to figure out what exactly was wrong I opened his dialogue file in the Dialogue Editor thinking that maybe some flags are set incorrectly and hoping that at the very least this way I could finally read the dialogue I'm missing because of a bug.
Turns out, the line in question isn't even in the Arx dialogue tree.

For those who are curious what the conversation options in the missing dialogue look like:

On an unrelated note, I found the other missing dialogue line, the one where you can point out that he doesn't seem very happy with your, errr, mating ritual that can happen between acts 1 and 2. That line didn't trigger for me in game, but from the look of the nod I can't tell what exactly is wrong.

Also, if you run search by the word "flesh" it sends you to this very nod, except there is only word "bone" in it. I'm very confused. Perhaps it got removed?
TL;DR: this is frustrating as the dialogue is clearly there in the files, but we can't get it in game. Please, please do fix this.
