Ondis, thank you for the feedback and the ideas!
The first three things can TW do if he thinks they contribute to the mod!Change left-right wing slider to something like civil libertarian-conservative or progressive-absolutist.
Change national relations, manually. Croatia shouldn't have +2 with Serbia just cause it's "close" ideologicly.
Fix the thick black lines.
For the future I also belive that if possible alliances should be made impossible from the diplomatic screen. Instead they should only be possible to form through scripted event. (So that people don't go on influencing Serbia as Albania or something and conquer the whole of Yugoslavia, I mean sure - freedom for all to do what they want in the game - but I think this is just stupid for this mod. Also the AI could do unrealistic things like this with the massive IC the countries get.
Otherwise I like it. Also if you want add that it is compatible with AoD - at least if no techs and units isn't a bug.
About alliances, you will be able to make alliances ans such but of course then you won't play historically, so if you want to play historical, then you shall just follow the events
About AoD, let's wait for some more playable versions
About Western Bosnia, well they will be in alliance with RS some periods.
NO MORE ADDING OF PROVINCES ON THE MAP!
NATO will be there like a off-map country but not single countrys like Italy and Russia. But of course there will be events that gives Serbia Russian volunteers and same with Bosnian weapons from Middle East
