I've been playing this mod in the last couple days, and it's mostly been great, but there are a couple problems I noticed.

First is that the Muslim Europeans are seemingly supposed to be in the Turko-Semitic culture group, but instead they're a separate culture group called "[garbage charactes] turko_semitic".

Second is that the AI will never, ever colonize provinces in the Venice trade node. In my first game, Rum colonized all the way north into Germany, overseas in the Americas, but neither they nor Magyaristan nor anyone else ever settled in the Venice provinces.

Third, the Po Estuary modifier doesn't appear in Ferrara despite being in the files (I checked), nor does the Center of Trade modifier in Venezia, so the Venice node is basically worthless. (Connected to the previous? Maybe.)
