Hello Karl,
nothing related to vehicle.add was changed deliberately. The problem may be
related to vehicle insertion.
Here are things you could try:
- force the vehicle into the network using vehicle.moveTo or
vehicle.moveToXY (if that works the issue is with insertion)
- activate debugging code in MSLane.cpp:70 ( DEBUG_INSERTION) and activate
the line /#define DEBUG_COND2(obj) ((obj != 0 && (obj)->getID() ==
"yourVehicleID")). This will report the reason why the vehicle
'yourVehicleID' is not being inserted

regards,
Jakob
