Logan with the bandit must happen before the bandit quest ends no? And the bandits together is random when you explore the camp? I explored a lot and besides the dialog haven't found the CG. I saved the lizard tribe but didn't get a CG. Didn't get the nauxus either. By the way do you get to do more stuff with him if you don't escort him away?
No I finished it and still find him and the bandit at his place during the night, and the two bandits is a random event in the camp but I'm unsure if it still appears after completing the quest as I didn't check. And saving the tribe the CG is when Othra and Roushk hug in the lake after curing Roushk. With nauxus I didn't know you could escort him away, so I don't know what you mean by that. If you mean helping him you do get some more stuff to do with him.
