I am experimenting with various options as the Reds in Drang Nach Osten, which looks like a fascinating scenario even though huge, and noticed a few things and have a few questions.
If I accept the German ultimatum and genuinely accept peace, I have noticed that all Red units in the Ukraine will disappear from the game if not evacuated from the Ukraine immediately. I would suggest that the game messages make it absolutely clear that the player must remove all units from the Ukraine if they chose to genuinely accept the German ultimatum or have the game automatically redeploy the units back into Russia. If the Red player does not evacuate those troops in Ukraine on turn 1, large numbers of troops just evaporate. (Also there are some locked troops which can't be evacuated out of the Ukraine including the Red Don River fleet plus admiral. I would suggest they be unlocked to allow evacuation if the Reds genuinely accept peace to allow their evacuation.)
Even after evacuation, I noticed the Ukrainian areas just evacuated are still designated as under Red control. On the next turn, I could move Red troops back into the red controlled parts of the Ukraine if I wanted but not the regions originally controlled by the Ukrainians at the start of the game. Is this intentional or should the evacuated regions convert to Ukrainian control and become off limits to Red entrance-until war is officially declared by the Reds at a later time?
I have noticed that the Germans and Reds have access to each other across their border between Russia and Poland where the Belarus and Mazollia provinces intersect-even though they are at peace with each other. Attacks can be launched through those two provinces even during peacetime. I assume it is a bug. Shouldn't crossing into enemy provinces be off limits to unfriendly troops until a state of war exists?
If the Reds genuinely accept the German ultimatum and later declare war against the Balts or the Finns or the Ukrainians or the Transcaussians, are the Reds automatically at war with the Germans? I declared an attack on the Baltic states and noticed that the Red-German relations dropped to 20, which is low, but I assume still not technically at war. I am guessing if I attack another country other than Germany or German troops, even a client country, a state of war doesn't technically exist until the Germans select a diplomatic "go to war" option? Is that correct? (I am partially asking this question because of the access between Reds and Germans at the intersection between the Belarus and Mozollia provinces.)
(IIRC, relations are described on the objectives page and +100 means allies, 0 means neutral and -100 means enemies at war.)
