In the codex, when opening the 'Duplicant Jobs' menu (which shall be renamed btw), I can click on each skill to read the description.
However, when unfolding the 'Index' menu and clicking on the Duplicant jobs entry, all the links in the description window are broken
Steps to Reproduce
On the codex, check the different ways to show skills descriptions.
