So I'm unable to recreate your error here... not finding anything wrong with any of the shipsets/races. Perhaps consider:
A) What version of GC are you on? 3.05 Beta?
B ) Re-installing the mod fresh. Ensuring you delete ALL the race files for them. Its possible you didn't replace them in the past and they are referencing old files.
C) Recreate the shipset from scratch using the in-game fleet editor... they won't be perfect (missing fighters) but it should avoid needing mods enabled for future races.
PS: The Lythian icon should be: GRM L Flower (All Blue)
This will be fixed in the next release.
