Ai path in WCU are weird

So I was doing a bus route and because I am in beamng and have no patience at all I was speeding. All was doing ok grandma was happy to go home faster but when I arrived at the forest house (the one that pass near a house), it start to be a real challenge (I was driving on the line 1). In this section, cars tend to go on the opposite line (and thats make speeding with a 10 tons bus on a narrow road very dangerous). It's not the only place were AI path are weird on this map. Sometimes, car tries to avoid imaginary objects like for example on the road between the long sea bridge and the higway.
Tell me if you need more info, problems have been tested in safe mode.
