I think I softlocked myself.
I'm currently in the Quest to bring Chloe to Ramoray , to unlock the lab. I talked to Stella triggered the talk with Ramoray on day 65. I'm now on day 68. But everytime I go to Chloe to get her she just say's: "Leave me alone, I dont want to talk to you. Come back when you want to have s*x with me." Or something similar to that.
