I managed to solve it myself. The problem was that the font size was 1.25 in ingame.menu. Changing it back to descScale 1 solved it. I'm leaving this post here for anyone else having this similar issue in the future.
The solution which I wrote IS for Academy: Outcast mod. The solution:
So first you need to download Blender (it worked with ver.2.79b) and a plugin Blender 2.64+ - Jedi Academy Plugin Suite v0.2.2 (BlenderJAPluginSuite0.2.2.zip)
Download Blender (simply Google it) and the plugin is in the Downloads section in JKHUB.
USE this tutorial

Follow everything in the tutorial except for one thing. Don't use the JEDI OUTCAST GLA file. Instead use the GLA file (You need to extract it from the jaooutcastv1.00a.pk3) from "Jedi Academy - Outcast v1.00a".
When you extract it, it should be located in "\models\players\JK2anims\" in your JA BASE folder.
During the tutorial, when asked for the GLA file, you need to choose the "JK2anims.gla" which is now located in "\models\players\JK2anims\"
Copy this code, when asked:
skeleton = bpy.data.objects["skeleton_root"]
for object in bpy.data.objects:
if 'skin' in object.modifiers:
object.modifiers["skin"].object = skeleton
I'll add this solution to the first page in case anyone else needs it.
