'False' Family Tree Error?"

[Live2sculpt]

I seem to remember encountering this before, but can't remember how it was solved.

Editing PSFs into SS, I get an 'error' in my script that reads like this....

"19:24:56.328 [script.err] [error] Script Error in mods/SS6.3/data/world/maps/campaign/imperial_campaign/descr_strat.txt, at line 6136, column 14
Eustache is a character but not a named character and therefore cannot exist in the family tree"

...Which is utter bollocks of course. The character was doing just fine before.
In fact, I could remove this character from the script, and the game would just present another perfectly good name as broken in its place.

This is clearly a false error, but what is the cause? I need to get past this to resume my testing of the script.

*edit* AH! I remembered an important part. I added in another modders garrisons without checking against duplicate names.
