So I'm having some trouble with the Cumberland Charge scenario. Before you enter Cumberland Terminal, you're asking permission to proceed to the terminal and the permission is given. However, there is a red light blocking my way and no matter how long I wait it won't turn green. I restarted the game multiple times, tried setting al the switches correctly and waited at least 15 minutes for a green light but nothing happened, in other words, I'm stuck. Does anyone know what I'm supposed to do? Or is it a bug in the mission? I'd rather not redo the entire scenario because it takes quite some time to complete, and I'm not even guaranteed that I can even complete it without problems.
