Nvm I was wrong, Tara part was CAAB 14 so there might be a completely different problem at play there.
Also it's nice that you intend to play through the whole thing. Even if you disregard any problems with the clarity of the quests playing through the whole thing might give you some perspective for what'd work well or not for the flow of the story. Just be aware that for me personally it takes some 2 days(or more) to play through the whole thing if I read everything so unless you intend to skip a lot it will probably take you a while.
