I've noticed during the Baltic Civil War, as Germany if I am to annex Latvia and Estonia, no descision pops up, leaving a pretty bad bit of border gore.

Is it actually wanted in the Christmas Truce update, that all the socialist uprisings (especially in Europe and the Reichspakt countries) get crushed within days? Hellenic Socialist Republic stood a chance for like 1 week before they were crushed, Ukraine... 3 socialists troops vs like 50 from Ukraine? just a few days until it was over. And it looks like that kinda all over the world. Even France didn't mange to win a single fight so far. Earlierst the 2. Weltkrieg was over was in 1937 when French Republic decided to land in 1936 in south France, and then Germany went all in as well. Most of the time the ACW is the only nation outside Asia that might create a socialist country

Why is Egypt Allowed to take control of the Suez without a fight even tho I have battalions stationed there? It doesnt make since they wouldnt just say "eh whatever" when the egyptian army starts advancing toward them.

I love the mod, but I never really understood the navy in Kaiserreich after the update, it'd take years just to finish repairs on a single capital ship, if a ship in game was heavily damaged during a battle in 1939, then it's repairs would complete in 1941, heck 1945 probably

How do you play as the brazilian states? Is there a civil war that will let you play as one of them?
