There's a bug in the Linux version of GearHead. Fortunately it's one that's very easy to fix by yourself, and even to repair your save files. Because I wrote some filenames in the wrong case, the stories for HwangSa (and I think the Guardians) won't be loaded. Thanks to Shoujo Rat for pointing this out on the dev group.
Search the file ADV_FederatedTerritories.txt with a text editor (or do the same thing to a save file you want to fix). Search for the following line:
.monk <TS_MONK_*_Story.txt>
and replace it with:
.monk <TS_MONK_*_STORY.txt>
Do the same for:
.crime <TS_GRD_*_Story.txt>
Changing it to:
.crime <TS_GRD_*_STORY.txt>
This problem will be fixed in the next release of GH1.
