A few modding questions

[Raczynski]

So I've finally installed the demo and first thing I've wanted to do was some modding
I wanted to change some province names and types and names of baronies. I've changed names in map/definition.csv and the baronies in history/provinces.
Alas, it seems I've only managed to break the game: province names I've changed in files on map stayed the same while Boleslaw of Poland become unplayable and I've got "no_character" over his holdings. Also, for some one of the baronies in Kujawy become owned by Seljuks.
Does anyone knows what I'm doing wrong?

Changes to province (counties) and barony-names need to be done in the localisation-folder/text1.csv

Restore the other files to the original settings. Changing file- or folder names will screw up your game.

Thanks.
Sounds like more work though

Also don't change the tags (like b_xxxxx or c_xxxx), but only the names (the ones you see in-game) after that. Which is much less work then the things you have done I believe.
