Hi Well, other day i was playing Sand Patch Grade Fully fuelled Scenario on Ps5 version, i have done everything right like the game tell you to do, and about between 10km/15Km and going up the train starts to stop and going backwards, and i cant stop it, neither brakes works, failled the scenario because a red light. Yesterday tryied again in Xbox Series X version, in the same place start doing the same, i dont know what i have doing wrong. So i saw a video, and what i see? he turn on a switch in the back panel called comms and turned on a comms button in the left panel. I tryied and worked. Why the game doesnt tell me this? We have to guess this simple thing. lolll.
I had the same problem. I did the same search. I experienced the euphoria of the comms button. I never forgot to set it ever again.
