I could not pass the world level 4. The fact is that here the control points (they are not associated with a specific location on the map) change and you need to increase each of them to find the number.
I also had problems with this operation, we could not complete the delivery of the cargo, and then I decided to turn to Division 2 raid https://legionfarm.com/division-2/raids where they helped me complete this raid 3 times and get Eagle Bearer Exotic
