The title pretty much sums it up. I've made a passenger route (About 8 or 10 stops, and about 2-3 baseboards apart each). I have 4 portals (2 on each end) one is sending trains north, and one south and the opposing 2 are receiving the trains. If I am only sending trains north bound on my route, it will run all day, no issues. However, If I am sending south, it seems somewhere around the time the first train gets to the receiving portal, the game crashes to desktop. Im going to do some more tests, but this seems to be whats happening. Im running the Schedule Library and 2 Central portal controls to organize it all. I have tried running 1 central portal, same issue as well. Trains are spaced out 8-10 minutes apart. Any ideas? Thanks guys!
