I am testing Scenario 1914. Here is what I found:
-There is no Oil II, Oil II, or chemical resource in this map
-Unable to move early machine gun until Infantry logistics: hard to defend conquered cities
-Can't build any Biplane, Improved Biplane or Monoplane: "0 units allowed"
-No point to build Naval Mines until Naval Logistics, can't move them out of cities
-While playing with Austria: "Not connected to Trade Network" with Germany, even with Open Borders. WTH?
-Nations declares war in the same sequence as WW2, so you see Mexico always entering the war against Germany and Italy in 1917 +/-
But there in one BIG bug: conquering cities when you don't see which units are defending it. Example:
Now move Cavalry to the square behind the city:
SURPRISE! City conquered, no Cavalry lost, and all the defenders retreated south! LOL
Thats how I conquered Pristina and Belgrade easily.
I know, there is still a lot to do, but you are really close to get an outstanding Mod!
I'll keep on reporting my feedback
