So there is the case in this novel: Omae Mitai na Hiroin ga Ite Tamaruka! There is one group that is hidden due to dead links. And then, this group is "revived" and start posting update since October 17th: Spoiler: Revived group updating Spoiler: Shown in homepage However, the newly updated group is still hidden. Spoiler: Chapter list with 1 hidden group This makes me curious about several things. How long does it takes for NU to update chapter list when dead links/groups are revived? And what is the mechanism to decide whether a link/group is dead or alive? Does the admin check it one by one (seems like a very hard work )?
