Hey Crazy!
Thank you for your kind words/feedback. We greatly appreciate the support! Glad you've been enjoying your time with AHITR o/
Usually if the girls aren't in the room they're supposed to be for a quest, it means you'll need to either progress with the main story or progress the particular girl(s) story.
I'd recommend doing both Cait and Lyriels stories and seeing it that helps.
Let me know if that resolves it for you!
