Had a problem with one of our chapter titles having a carriage return in the TOC. Just fixed it! How? Changed the chapter header from
\chapter{Fundamentals of Django App \\ Design}
to
\chapter*{Fundamentals of Django App \\ Design}
\addcontentsline{toc}{chapter}{Fundamentals of Django App Design}
Hooray LaTeX!
@michal-h21, we ended going with your method. Thanks!
