two columns column breaks

Question

\documentclass[11pt,a4paper,BCOR10mm,DIV11,toc=listof,parskip=full]{scrbook}

class and two columns there via "\twocolumn". It works fine mostly but in some instances of the texts involved I have the situation that part of the text of the left column is not put into the next line, and thus seen half into the right column.

Interestingly it seems that there is some connectionn to () there as it always happened with text put in paranthesis. (Body) ,....

Is this a known limitation there that () text is being problematic? And how can I circumvent this problem?

Edit:

AS asked in the comments. As it seems the probblem only happens when something inside () is at the end of a line (in this case "Longevity" reaches into the 2nd column).

Also as it could be important: I'm using writelatex.com there to write the document (although not sure if it is only limited to there or a general latex phenomenon.

You will see the problem replicated with/without ():

\documentclass[11pt,a4paper,BCOR10mm,DIV11,toc=listof,parskip=full]{scrbook}

\usepackage[english]{babel}
\twocolumn

\begin{document}

\noindent\textbf{Ageless beings}: +4 CP
\textit{Life Support (Longevity: Immortal) (5 Active Points); Unified Power (Dragon; -1/4)}

\noindent\textbf{Ageless beings}: +4 CP
\textit{Life Support Longevity: Immortal (5 Active Points); Unified Power (Dragon; -1/4)}

\end{document}

Since you're most likely going to use longevity quite a lot in this document, add

\hyphenation{lon-gev-i-ty}

to your document preamble. It will add the hyphenation pattern for longevity to the list of existing hyphenations:

Note that you may still receive overfull \hbox warnings, which depend on your paragraph construction. Typically these are removed when reformatting the paragraph text, perhaps using \raggedright or even including microtype.

Here is an example with full justification (top) and \raggedright (bottom):
