Just finished it out (imperial side). Didn't notice anything game breaking, but I can confirm there are a few lines that are showing subtitles, but no spoken lines (saw this twice), and the two lines (four total, depending on which Stone you choose) don't appear to be there either, as was indicated in the description. I get the IMPRESSION he may be looking at some way of getting that line in (though it was never recorded, I don't think?). Also saw a few places where the dialog and the subtitles don't match (We should split us VS. That's where I'm going, you should come with me... the latter makes SO much more sense...), but only someone who has subtitles on all the time (me) would really notice that.
As to the issues I mentioned earlier, the walk-in-place bug is somehow tied to DYNDOLOD, though I'm unsure how exactly. I just turn it off until I'm inside the keep, and everything's fine. Likely, the audio starting off is tied to a mod I have somewhere as well (maybe Kill the Orchestra? It could be tied into an audio cue, perhaps...) but either way, those appear to be my line-up, not the mod.
Hadvar's voice takes a small amount of getting used to, but overall I think it was done better than with the voice we are all used to... much more emotive and in place, so to speak. Just better delivery overall. If the author takes care of those issues I mentioned above (and even if he doesn't, to be honest...) this is a REAL good addition.
