Well, after dealing with Esbern first not opening the door for me in a quest, and me activating clipping mode to get in and continue the quest - I'm having another issue, besides the fact I haven't heard a word of his entire dialog all game!
I'm with the greybeards and everyone at the negotiation mission. It's at the part where Esbern stands up and I figure he starts talking - however, nothing happens, it's like he stands up and does nothing. I have no text reply options, nor does anyone in the room even say anything. I left the game even running idle for 10 minutes, and same thing.
