I have been building a route using the YARN roads and intersections. My question is about the T intersections. There are 4 splines on them. One on the right side, one on the bottom side and 2 on the left side that are almost on top of each other. What is the purpost of the 2 on the left side? When I connected my road on the left side, outermost spline, it seems the other spline just disapeared. Could anyone inform me of how to connect these splines and what is the purpose of them? Running TS12 Build 48249. Thanks.........
