Does anyone know exactly when the transition point is between the V11 stack that's being used for freeways, and the V12 stack used for cities? I wonder if that transition could be related to this issue, like if V11 is initially making a bad decision that V12 needs to correct, or if a more limited version of the network (maybe just lane keeping and TACC?) is briefly running as it transitions between the 2 main network versions? How long does that transition take?
Hopefully once V12 is updated to handle the freeways as well this problem may resolve itself.
