Yes they have it, I just went there with the link you gave and I could read it, so I guess you have a problem with whatever you're reading with.
Hahahah, i took a look. Your right its not there. No idea whats going on but you should try and get in touch with them to sort it out.
mayb you can reach out to the kobatochan admins? no easy solution for this- their links aren't working.
Read up too 41 and go back to koba http://www.novelupdates.com/extnu/251604/ Or http://novelsnchill.com/everyone-else-is-a-returnee/eer-chapter-25/

No really, the link led me on a page with all the chapters and I could go on each of them ( I'm on my IPad by the way so I think your support is the problem ).
Pretty sure that you just have to wait for Novels&Chill site to start working again. It's down right now and i think those chapters are on that site.
