Hmmm had consistant CTD during rebel turn playing as Getai on 0.81v2.

Tried running EB without script - candidate for marraige popped up.

Restarted script = several turns later consistant CTD.

Applied permanent fixes and restarted from CTD point with script running = another marriage proposal and no more CTDs (lots of turns since).

I suspect there is a Getai specific trait error causing this since the 2 consistant CTDs I bypassed (first no script - 2nd applied fixes) had marriage proposals at the end...

Of course I reserve the right to be totally wrong :)
