I am having this issue still as well... I have tried everything suggested: Casted silence on myself to purge it on/off, killed one of my party members, loaded to an old save file, checked file integrity through steam, deleted AppData files, and several others I cannot even remember at this point. I am not using Mods and this happened shortly after Wither and returning to the surface. I am not restarting the game so I am at a complete stand still frown
