on two separate characters now, I have gotten a bug during the "Flawless Plan" quest in the TG quest line, where inside the al-Danobia tomb, Zeira refuses to start walking or continue walking. I have tried dropping the quest and still get stuck at the same area. The only workaround I have found is to "ghost run" the dark area to trigger the next part of the quest and skip the dark portion.
On the second playthrough, not only did Zeira refuses to start walking, but her dialogue would not progress. She would endlessly give you the same options/things to say as if you had not said them before, including the intimated line.
After ghost running the dark portion, you have to reloadui several times to make her spawn at your location, and its a bit iffy if it works, sometimes have to restart quest (and its an annoying one to have to keep restarting let me tell you!)
