Okay, so I have had a number of glitches, mostly involving dialogue.

My first problem, and by far the least problematic, is every now and then the dialogue will go silent for about a second. It's a bit annoying, and I miss a word or two, but I have subtitles on so I hardly even notice it anymore.

My second problem was more severe. It started when Lydia began using the "Throw Voice Shout" Dialogue instead of her own. I found out this was a vanilla bug, and I was able to fix it with relative ease.

After fixing the Lydia bug however, I found more broken dialogue. Scripted banter had completely ceased. For example, when entering windhelm, instead of the local nords picking on a single dark elf, they all were just standing around looking at each other. I walked around and found the same was true with all scripted dialogue in the city. I reloaded all of my earlier saves, and found similar results. I ended up making a whole new character, (Which seemed to fix the problem.)

Which brings us to my current unsolved problem. I'm currently in redwater den, (On the quest for the chalice) And whenever I drink the redwater skooma, I am transported to the cell, and the high elf dealer says her line of dialogue, but than when the vampire goes to reply... nothing! The vampire doesn't reply, and I can't move, all controls are disabled, and I'm forced to reload. The strange thing is, everything worked fine the first time, but than I died and haven't been able to get it to work since, (even if I reload earlier saves and start the quest over). I tried the alternative (Smashing my way through) but I found that banter dialogue is broken. A character will say his lines, but when the other character is scripted to reply, they don't. Combat lines still work, but all banter seems to be broken. I don't know if this is just redwater grotto that's broken, but I really don't want to have to start another new character. Help?

UPDATE: I believe I have finally solved this problem (A few months later.) I found UFO to be the most likely cause of the problem. After uninstalling UFO (Ultimate follower overhaul), I found that the dialogue began to work again.I have reinstalled UFO, in hopes that it was just a faulty installation.
