My group shares the same issues with multiplayer and dialogue #3, #6, & #10. A lot of the time, friends just do not realize there's chatting going on; the ear icon is so tiny and on the edge of the window that it's easy to miss when attention is focused at the center of the screen. We are constantly streaming in Discord to ensure each other is following along, but some of the story is still missed.
Just last night, one member of our group missed the Bugbear and Ogre barn scene, which sucks. The character was in proximity but from their perspective, the rest of the group we just idling outside the door.
