[quote=bcorn77]Try "1" or "spacebar" on your keyboard during the part of the conversation that won't proceed. It's a workaround that's gotten a number of us out of a tight spot with conversation bugs that wouldn't allow us to proceed; this way you can play on until the devs fix the reported bug.

Unfortunately that for me didn't worked, there's already a thread about this issue (I'll link it down in my reply), essentially the game for whatever reason when you talk with Pooldrip after killing BOOAL thinks that you're in a co-op session and so it begins a vote to see which dialogue option pick, after you cast your vote it makes you wait for the other players choice but since you're the only one in the session it gets stuck...
