I'm doing Caitlin's personal quest and on the step where I collected both water samples and the journey told me to wait for a day or two. But it has no count down timer like 'A Sisterly Dilemma' or 'Fort Sera' and it's almost a week without update now. What should I do to progress this quest further?

have the same problem

Caitlin needs to be a slave in order for the quest to progress. If you've freed her you will need to enslave her. As soon as you do that, it should be working normally.

...I feel like this is more of an oversight on the dev. Since her talk option implied that you need to treat her well rather than treating her like a slave. Plus the player can initiate the quest after freeing her.

But thank you very much for explaining how this quest's trigger works!

I'm having trouble with the my beloved father quest. I'm trying to get the codes and noting is working. It makes me angry trying to figure out, so if anyone knows the code please let me know.
