Ok, so i found out the reference system, it was pretty weird and im still trying to wrap my head around it, if someone is interested in knowing I can try to explain it.
But i havnt found out why i cant play the game in mutliplayer if i extract the file "Divinity - Original Sin\Data\Mods\Main\CharacterCreation\Properties.lsx" from main.pak. Then it says the main.pak is corrupt and i cant play the game in multiplayer, >even if i don't modify it in any way< O.o
