You have been doing your best and besieged thousands of Bases last week, right? Then you recalled troops and continued occupying Bases; however, you have not received any new Ranking points. Here's a thing: you receive 100 points in the Weekly Occupation Ranking each time when you occupy a Base.
The Weekly Ranking is updated every Monday at 7:00 AM UTC for all players around the world (even if you play from the North Pole). At that time, all Occupation points earned last week are reset to 0. Hence, when you start recalling troops from the occupied Bases, you get -100 Occupation points each time.
How do I fix this and start receiving points again?
There are 2 solutions:
1. Having recalled all your troops from the occupied v, first, you need to occupy some new Bases and earn new Occupation points to reach 0 value. After that, all further Occupations will be bringing you points for the current Weekly Ranking.
2. An easier way is to wait until next Monday when your current negative value will be reset to 0 automatically.
