I decided to start TOB on a new character, and I inported her from SoA, and all went well, until it came to adress the soon-to-be-dead bhaalspawn. When I talk to her, I see her portrait, or avatar rather, but no text. If I have an option to choose a reply, there is no "End Dialogue" button, or "Continue" button, I have to click around the box. So apparently, the game knows that there is text there, because I can reply to it, I just don't know what I'm saying. I'll post an example below:

As you can see, at this point I would have to click aroudn where I think an option of reply might be.
