It appears bookmarked, but it doesn't appear on the lists. Edit: Sorry I forgot to mention that I'm using the web version on Fİrefox Linux. It works on the Android app.
Where in the library are you looking for it? Did you add it to a specific section of your library?
I tried adding it to Reading tab like all my other comics, or Dropped tab. It doesn't appear on any of my tabs.
@humanhooloovoo this is fixed - thank you for reporting!
