Aside from fixing the glaring economic balancing problems I'd rather have PI focus on fixing stuff that's still left over from old Victoria 2. While fixing the economy will prevent the Intervention CB spam, it won't fix the still ongoing Russian Wars for Northeast England. Non-core Demand State wars should not happen in Europe unless the attacker is fascist or communist. It just doesn't fit the period (this is not anything goes EU3). Mods have managed to make this a rarity, PI should be able to do this too. The second thing is fix the 1836 scenario. You're going to be rifling through the history files to fix the 1861 problems, so why not combine the two and make both scenarios a little better. What needs to be done:
-Remove EGY cores on the Levantine (and Crete), it conquered 6 years earlier to act as a buffer between the now autonomous Egypt and the Ottomans. It wasn't claimed nor were they core Egyptian lands.
-Give BRZ Marabitas. It only appeared on a few early 19th century maps as Colombian. There was no war or treaty that handed it to BRZ, so it was BRZ all along.
-Give BRZ Tarauca (aka Acre). There was no war over it and since you'll probably won't write an event for it, it's best to give it to BRZ.
-Remove the BRZ core on Iguatemi. It was taken during the War of the Triple Alliance as a spoil of war. It was never claimed by BRZ.
-Give PAR the state of Alto Paraguay. It had to fight two wars over it, of which one they lost. Can't do that if it isn't theirs.
-Remove CHL cores on Atacama. The War of the Pacific was a war of economic opprunity, to capture the rich Atacama region. They Chileans didn't have an historic claim nor was it core Chilean territory. The AI should be convinced to capture that rich region on their own.
-Remove the colonized bits of British Columbia and put an automatic NF (like you used on Washington and Oregon for USA) of ENG on it so the AI will colonize it. It'll allow the USA to have a shot at gaining a non-ugly Columbia.
-Make Coeur d'Alene in Idaho terra nullius, it was part of the Oregon Country and thus not part of the USA.
-Give Colorado and Oklahoma to the USA. They were only contested in name. Mexico claimed a small part of them but never sent more than a lost hunter to the region. American presence was much greater. Also allows the USA some NFs after colonizing the Oregon Country. Additionally the Trail of Tears happened in 1838. That's only possible if the US stops colonizing Oregon and sends troops to colonize faster. They wouldn't have sent entire tribes there if it wasn't part of the USA. Sure it was mostly unsettled but so was half of the Lousiana purchase at that time.
-Make the part of Mexico that is now American into colonies. They were colonies to the Mexicans and they were colonies/territories when the US took them after the Mexican-American War.
-Make the parts of Sokoto that are in Cameroon terra nullius. They never reached that far.
-Make Zomba part of the Kazembe region. Otherwise Portugal will always get half of Malawi, which was British.
-Improve the relations of POR with OMA. The Portuguese were in no position to fight a colonial war in the region, but the AI will always take Omani Tanzania and Kenya.
-Replace Hedjaz and the northern part of Yemen with the Ottoman Empire. Hedjaz didn't rise up till the fall of the Ottoman Empire after WWI.
-Kaf should be wholly Nejd.
-Tarfaya should be terra nullius. The Spanish had made a deal decades before 1836 that specified it didn't belong to Morocco.
-Redo the borders of the Central Asian khanates. My 1836 Improved mod has much more accurate borders (checked out 19th century maps for it).
-Give Nyda in Siberia to RUS. Prevents other countries from colonizing the middle of Siberia.
-Remove EGY cores on the Levantine (and Crete), it conquered 6 years earlier to act as a buffer between the now autonomous Egypt and the Ottomans. It wasn't claimed nor were they core Egyptian lands.
