[babasoji]

Hello all. Please i need help because my igo8.3.4.142975 does not avoid London Congestion zone despite the fact that i have tick and untick period charge, Per-use toll and Permit needed several times. Please does anyone know where i can tweak it.

See my sys.txt below

allow_charge = 1
allow_ferry = 1
allow_highway = 1
allow_special = 0
allow_unpaved = 0
