(Just passing by as the twcentre appears to have messed up its forums FTB.)

Kingmaker bug is fixed by either getting quark's latest traits file or even (if you please) getting the latest 6.2 beta patch.

A DIY fix entails:

open the export_descr_ancilliaries.txt file and place a ; (semi-colon) in front of all the trigger lines from

Trigger KingMaker1
down to
AcquireAncillary kingmaker2 chance 40
(inclusive)

hope this helps.
