Yep they do. I read this comment that said:
Initially, Solo Leveling Chapter 156 was meant to release last week on Thursday, June 17th. However, a couple of days before the chapter’s release, D&C Webtoon announced that the series would be on a break because of the author’s bad health. And recently, the platform confirmed that they are extending the delay for one more week.
“Sorry for the delay in the return of Episode 156. In order for the author to fully recover his health, the DNC Webtoon Biz editorial department will also provide full support. Thank you to all our readers for your patience. We ask for your support so that the writer can have a good life,” said D&C Webtoon in their announcement.

Not the “good life” they make it sound scary
Does the author have an illness or something else? The same thing happened in the beginning of the year so I was just wondering if they had a long term issue
