Here is option to delete all Europe map. It is useful for ferry-addon maps, like ROC, or for far away addon maps, like Russian open spaces. Now you can drive only on addon map(s). I kept Calais for ferry connection. The reason is: when I wanted to drive on addon maps and searched for job, mostly they are from one european city, like Rotterdam or Lille. Then I drove many times on same roads and it became boring.
It is also very useful for modders. You don’t need to open and save whole Europe every time.
