Credits Deduction even after end of Game World

First of all, I wanna say that I am a big fan of the Domination gameworld and I have completed two seasons. But I just noticed now that I continue to be deducted credits even when the gameworld is no longer active. I am eagerly waiting for VI but I don’t feel that it is fair to be losing credits over a gameworld that I can no longer access. Is this a fluke or is this an actual thing?

Domination is still going for another 11 days or so, just closed for new registrations: https://domination.airlinesim.aero/
