I made it to Moonrise towers in my current playthrough.
Knocked out Minthara at the Druid''s grove in Act 1, and found her in the MT prison. I let the guards stop their torture and helped Minthara release her mind from the absolute.

I then fought and killed all the absolutists in the prison area.
After that Minthara had become unresponsive. I can't talk to her and she won't move.

I went out, killed all the guards on the docks and returned to the prison, but Minthara still just stands there, unresponsive like any barrel or burlap sack.
A bug ? Or am I still missing something ?
