With the new version, everything started working fine. The button I wrote about worked, and the collapse of Austria-Hungary collapsed with minimal delay, so I'm very grateful to you.
But I noticed something you missed in the game:
1. In the collapse of Austria-Hungary, Italy and Romania don't get Istria and Transylvania.
2. After the collapse of Austria-Hungary, I didn't notice any Southern Polish uprisings against Austria-Hungary or Western Ukrainian uprisings.
3. After the collapse of the Russian Empire, I noticed that Kuban and the Cossack Republic/Uprisings are missing, and also about Moldova. 4. In some countries, it was possible to create a state (for example, Austria could create Austria-Hungary), but there are also countries that cannot be created for them. For example: for Austria in (Austrian Empire), for Ukraine in (UNR/Ukrainian People's Republic), for Belarus in BNR, for Moldova in MDR, and for Greece in (Greater Greece, not Byzantium).
5. I noticed that on the map of Europe, the HRE was smaller than in Europe 4, and the borders are also imprecise.
Therefore, I ask you to correct or change something.
