I have a big problem. In Surveyor mode, all of my junction levers are present. When I go to Driver mode for the first time everything is ok. But when I save my progress and I reopen it to continue, some junction levers are missing. if I go back into Surveyor mode all of the junction levers are present. I am running Trainz 2010 and I am at build 49933. Does anybody know what is going on?
