Isn't this fixed in the just released 3.0.3 patch?
I gave the new patch a shot, and I did get some new lines while Zoe is being brought into the enclave for interrogation from Lihko, Enu and Shepard, and they DO say they knew of Na'ane's betrayal...... but then Na'ane is still standing in her room, and Kian still says he kept her secret? Is that right? They say she is in a cell but she is standing in her room, and I don't see any bars. And the way Kian words it could be interpreted as he not giving away her secret, and she did herself, but it can also be easily understood as being that her secret is still safe. So, either it's still bugged or I'm not understanding the course of events.
