Thank you guys for your answers. Quick update, BP event fired mid 1942, and I chose to release puppet nations. Now I´m gonna start a new game, cause my strategy needs some rethink on what to do about the allies. If you allow me, I´m going to share my thougts after a couple of runs:
-As Germany, I follow the Ribbentrop strategy instead of Generalplan Ost. Since Germany lacks the numbers to settle such huge empire, I prefer the idea of creating a powerful core in the Middle of Europe, and use puppets as a shield and for resource farming. More or less what the soviets did with eastern Europe. I would like to divide some countries even more, because my goal is to remain as the sole superpower. Do you have plans to add more chains of events for this? I would love to release i.e. the Volga German Republic, Don Cossacks, Brittany, Normandy, Catalonia or Galicia (I punish Spain for refusing my alliance offer). I saw other mods that let you do so. Also polish borders under a fascist regime need some changes (they should lose Bialystok and get back Lvov.
-How do you manage oil? By june 1942, I have defeated the soviets, but my oil reserves are down to 0 even if I control Baku and/or Iraq.
-How do you activate SS units for production?
-How can you get the partition of Turkey event? I got the invasion oone, but not the one after their defeat.
-Is it worthy to invest in AA, forts or radar to turn Europe into a fortress against american air raids?
