Here’s the link again:
There was an issue with the wrong sample additional browse paths being shown in the guide but it’s fixed now. Sorry for the inconvenience.
The difference between “Additional Browse Directories” and “Additional Source Directories” is that the browse directories point to the folder where the arz file lies while the source directories point to the extracted expansion files.
For example, the Additional Browse Directories should look like this:
C:\Program Files (x86)\Steam\steamapps\common\Grim Dawn\gdx1\;C:\Program Files (x86)\Steam\steamapps\common\Grim Dawn\gdx2\
And the Additional Source Directories:
C:\Program Files (x86)\Steam\steamapps\common\Grim Dawn\Working\mods\gdx1\;C:\Program Files (x86)\Steam\steamapps\common\Grim Dawn\Working\mods\gdx2\
