Apparently this is from my log when I was trying to take the settlement of Zangooose as England, damn thing closes out with a unspecified error. No mods are installed other than Stainless Steel and both Medieval and Kingdoms are up to date in terms of patches. Any help would be appericated .

The best I can do, I'm afraid, is to refer you to the Stainless Steel forum at twcenter.net, it's in hosted mods for kingdoms. You'll probably have more luck there since many of the mod contributors frequent those forums.
As for a remedy, I guess the old reload a save from a few turns back and do something different may resolve the issue. Sounds like it has something to do with your king getting the ancillary Kingmaker, but that might be of little use...

Good luck!

(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.
