I'm pleasantly surprised with the update. I really enjoy this expansion and patches keep this game playable.
However, I really don't find this new terra incognito feature useful. Black spots on the campaign map really fires up my vertigo. There were enough impassable terrains in the 1.03 and it was making the same point really. But the biggest problem is that now it's impossible to grant independence to several countries (e.g. India) because some of their minimum required national provinces fall under terra incognito and "db/revolt.txt" is not properly updated to reflect that.
Also, I noticed that in 1934 scenario, Finnish Winter War and Second Sino-Japanese War never occur. Although I'm not sure if it was always the case or is this an intentional change.
Long story short; please look over these issues if you have the time and thank you for your efforts.
Keep up the good work!
