Since I have lack of motivation to continue this map combo, unfortunately Adventurer's Combo project will be discontinued starting with 1.48 update. From now on I recommend you migrating to GMC Logistic's Map Combo since it has easier installation of map combo and you can select the mod you want to use.
For those who wish to explore around the world.
Adventurer's Combo is the project for Euro Truck Simulator 2 and American Truck Simulator which keeps everything simple while allowing you to travel around the world without getting you bored.
America (Coming Soon)
