I just started a new route in TRS2006 and rather than using the imperfect splined tunnels thought I would try the dighole type. However I'm finding these somewhat erratic in behaviour. On occasion, I'm laying the portal (UKTunnel1) and the track and spline points aren't appearing. Delete and attempt to relay a couple of times and the object appears correctly. Then, on trying to attach the splined tunnel wall, it's attaching the spline point at 180 degrees to what it should - i.e. leading out of the portal not to follow the track. This is sometimes happening on both portals.
Is there something I'm doing wrong here or is this a known bug?
