I have a very annoying problem with some of the polish freight wagons, maybe someone knows how to solve it: when i attach a loco to a consist that contains Gbs or some Z wagons the locomotive is dead. The only possible way to make it work is to dettach it from the consist in Surveyor mode, start it and attach it in Driver mode to the consist. Otherwise the loco is dead. No engine sounds, no pantograph, nothing works on it. How can this problem be solved? Thanks
