Other details

Also on 1.1.18 EDIT: I noticed the bug is triggered even with these steps (making it a worse bug):

1. Go to a random novel
2. mark as read the first chapter
3. open the second chapter
4. Exit the reading mode, Go to another novel and Mark as read ALL chapter.
5. Go to History section and resume the reading of the first novel menzioned (1.) with it.
6. click in the middle of the novel (summon settings)

So the bug is triggered even if you mark.as read all chapters of a another novel.
