What causes the error message that says: “A fatal error was detected in the leader- follower chain.”?

There are multiple possibilities for the leader-follower error. One possibility is that the network geometry involves a cloverleaf where a vehicle, in searching for a leader, follows a path that leads to itself as its leader. There is a work around that involves breaking the path so that a vehicle will not find itself as its leader. One way to accomplish this is to break the loop by adding a small NETSIM link in one of the loops of the cloverleaf. Another solution is to break one of the full auxiliary lanes between connectors into an acceleration lane followed by a deceleration lane with at least on foot separation between the two. The NETSIM link solution is probably the cleaner of the two because you can maintain the cloverleaf geometry better. This problem is more likely to occur with networks that have very few vehicles but can occur in any network that has a continuous cloverleaf. Another possible reason for this error is due to short link lengths, which can cause a corruption in
