My exact same map with the provinces.bmp was working when i did it manually. And i think everything in map looks fine atm, i even tried getting a clean map folder copy from ck2 vanilla and adding in the adjacencies.csv, definition.csv and all the bmp's + colormaps but still the same crash on the play button of the launcher. The generated files outside of the map folder look fine as well... :/
EDIT: I've been searching through my mod files but i really can't find what is causing the crash, everything seems like what its supposed to be. :C
