trying to write this without spoilers
I have been going to camp and then after resting, my party is placed in a completely different area than I started at. For example, I have rested right before entering the goblin camp and woke up in the forest, in a cellar at the blighted village, and once even in the owlbear cave.
I went into the goblin camp with shadowheart and did the volo mission, then went to the camp. so I could swap for Wyll. Shadowheart stated her problem and then the cut scene was stuck with me and Laezel looking at her. No dialogue options ever appeared.
About Shadowheart.. try hitting the space bar, it brought up the dialogue options for me.. I had the same problem.. Hope that helps while they fix it..
I am also having problems ending up where I didn't start out.. I Believe it is taking me to the last place where the character was before I left him at the camp.. so for me He ended up in the swamp, the rest of us went to the beginning of underdark.. but if I put my main character in charge of going to bed, all 4 of us went the wrong place.. <yeah, who knew this made a difference, I was making sure the new guy had the best armor etc, and then tapped the bedroll> LOL But.. if you are desperate, you can use the map and get back where you were pretty fast.. hopefully.. <I was near a portal>
