I don't know where else to post this, so I hope this is the right place. I'm enjoying the DLC quite a bit, but I ran into a scripting bug when I first talked to Graham. This isn't a major bug, but I think every bit of feedback would probably help to make a more polished product. When I first spoke to Graham after entering the Angel Cave, I decided to tell him that I killed Caeser first before asking about the other issues. After he responded to my comment, we discussed Lenius, and how he felt the Legion was doomed without Caeser. After that dialogue sequence, the conversation window terminates because it assumes that we're done talking for now. When I manually speak to him again, instead of all the options I had previously, he only questions me about helping his people and my only available reply is to say that I'll be on my way to help find the supplies for Daniel. I didn't even know who Daniel was at that time, or what I was supposed to be helping with. If I pick that option, it starts a bunch of quests without any context whatsoever, and he terminates the conversation again.
That was really confusing, so I loaded the autosave, and picked the other dialogue options instead before telling him that I killed Caeser. That worked and everything proceeded naturally. But hopefully this bug can be fixed so in future for players who pick that option first don't end up feeling very confused.
