Thx Nuttz!
Unbeliavable: "fairy play" in the war! ROFL!!!!
I made Murmansk Railway about 80 miles long to my "Finnish-Russian 1944 Continuation War" map...
Then I tested my first railway in Offline and thought what the hell is in my Bf109 G2 'cause it can't catch that rusty Russian train!:D
Now I understand. I must use couple of intermediate stations and cut the railway to short stumps and resuply intermediate fields that are near the main railway. Right?
Then next problem: I made couple of long railways and roads (between 20 - 50 miles) together about 300 miles. Then it crashed the Terrain Editor program. I think they are too long and that is the reason of crashing. Right?
