I have just still installed patch 1.2 and the issue persists. I am stuck in "with a little help from my friends" in the "discuss plan with the nomads" step. They stand there staring at me (Panam has a really flexible neck btw) but no interaction is possible. I have finished all the other quests so loading a previous save and replaying the mission is not possible. I guess I am f****d and will not get the Aldecaldos ending.
