I have already done that, I kill Selye, talk to Thane, and then try to talk to Nauxus only to get sent away. My other issue is I can't trigger the sex scene in the throne room, I have done some more research and I think it's something I did really early on in the questline, which is a shame because I don't have a save that early and am now restarting the game :/.
I will also mention whenever I help out Nauxus with the lizards I can't tell Thane to move in then proceed to get a bad ending in the questline where half the lines about how the tribes are at peace and the other half is about how they are at war.
Thank you for the help though!
