Help please!

Hi, today I was playing my dominions peacefully, minding my own business when suddenly an evil error appeared. When I try to finish the turn I get the message "Något gick fel! kv bad item mt0". If anybody knows how to fix this I would greatly appreciate any help.
The mods I got going are Cross path combat spells, Pax Malazcia ( the team I am currently playing) and Conceptual balance 1.4.

What patch version? If you have 3.23, then you need to download 3.23b and install that, because it fixes a bug that causes that error. If you're running 3.23b already, then you need to look at mod conflicts.

Thank you Edi! The patch was the problem, had totaly missed the new one. :P

I don't believe anything in the Pax Malazica mod would cause the error in question, so I imagine it's as Edi says.

(On a related note, it apparently has quite a few incompatibilities with newer CBM version, and a few other bugs (mainly with Coltaine's auto-summoned cattle dogs turning into crazy baby-eating women when killed), so I'll look into updating it over the next few days, hopefully with some additional content as well.)
