Where the Dead Ships Dwell: Unable to complete quest

Windows 10, Game Version 1.1.1

Hi there! Had a bit of an unexpected bug today when I was given the “Spiral Shell Peddling” quest in Where the Dead Ships Dwell. Cleared out the entire floor, but had no quest completion to show for it.

Admittedly I didn’t actually notice that the quest was incomplete until I was getting ready to leave, so I’m unsure if I wasn’t given credit for shells I picked up or if they just chose not to spawn at all. Sorry I couldn’t be of more help. :c
