So I'm cleaning out the CG room right now, and am currently stuck on Grey's Beach scene... I've done his sword quest and he keeps telling me not to ask about the artist when I talk to him in the sleeping chambers, so I'm only missing the Beach scene in the CG room. I know from looking into things that I need to start doing "adventures" with Grey to trigger the beach scene, but I have no idea where to start that quest chain.
On a completely unrelated note, I think the quest "Steam Gun" might be minorly bugged in my version (23.12.16). I had the Red Flower Crystals and such in step four before having the Fabric in step 3, so when I went to turn the latter in it finished the whole quest, but didn't properly trigger completing the quest on the tracker. Game still treats it as complete, it's just stuck on my quest tracker.
