question,

when promoting a general why does his unit cap still stay at 24? that is MAJOR turn off imo. I don't wanna micro manage it that much lol. any way to get around this possibly? I probably wont play much until its fixed, or ill just cheat my *** off using codes to work around the penalties of it.

ether way when promoting them they cap stays at 24.

constructive note for the Bulgarian country most of the focus in the tree that give Civil and Military factories plus dock yards are not for the core state province
that make them useless if you want to do the second balkan war at that point you cant win it at all only defend it and you still lose this territories and all the bonus from the focus tree but you lose them after the 1 ww too cuz the new country are create that the games prep it self for the 2 ww and you waste all that time to do them is pointless

the note is address to make the focus tree effect the core states province and not the one that are given to you after the balkan war because you lose them anyway

Would there be a possibility of a special tree for Argentina? Example, that you could decide whether to enter militarily or not through the outbreaks, that there was an approach to change their status and leave neutrality? Thanks, excellent mod

There is a big problem. While I was playing with The Ottomans, Italy is starting naval invasion to whole my lands. It should be more historically. And also I destroyed a lot of divisions of Italy, Italy had only 8 divisions but he was resuming to the invasion. This is really ****. Please fix it

i will reply to this whit

Spain remained neutral throughout World War I between 28 July 1914 and 11 November 1918, and despite domestic economic difficulties,[1] it was considered "one of the most important neutral countries in Europe by 1915"
Spain had enjoyed neutrality during the political difficulties of pre-war Europe, and continued its neutrality after the war until the Spanish Civil War began in 1936.[2] While there was no direct military involvement in the war, German forces were interned in Spanish Guinea in late 1915.

The Spanish prime minister, Eduardo Dato, a Conservative, declared neutrality by Royal Decree on 7 August 1914

i know it but i decide to copy paste it from wiki just because i don't want to write it

DOBO87, But this is not a problem, because you can win ww1 with German Empire and this is historical inacurate, so i don't see problem in this, Mexico are the same.

The reign of Alfonso XIII (1886-1931) remembers the catastrophic Spanish-American War of 1898, as a result of which Spain split with the Philippines and its last remaining colonies in America: Cuba and Puerto Rico.

i hope you get the point

Yes friend, i know all that, my point is that the game is not linear, you can have a complete alternative history.

A great mod and I'd give it a 10 if it was finished. It's still technically is a 10, but some miner issues need to be worked around.
