East Coast USA traffic completely broken?

I just loaded up East Coast USA and spawned some traffic to try out that new traffic light thing they added, but it is completely broken. Cars spawn in random places in the air and fall, drive backwards into walls, they do everything but drive on the road. Am I supposed to do something special now to get it working properly?

Edit: It only happens sometimes, other times it works perfectly? Its really odd.

 

I'm having issues with AI traffic as well, the vehicles spawn fine but they seem to lack awareness. I've made sure awareness is on in the traffic UI but cars constantly crash into each other.

 

Weird, when I did it they worked just fine for me.

 

Same, I got problems with traffic and with Script AI after update

 

I have the exact same Problem. Just freaking me out. Im braking and the car behind me is again just bumping into me.

In safe mode its "better" tho. They are at least sometimes braking...

 

I was able to get my traffic working again after disabling this mod: https://www.beamng.com/resources/advanced-driver-assistance-systems.17384/

I'm not sure if this is the cause or pure coincidence, but if anyone else has this mod enabled try disabling it.

 

Wouldn't surprise me, that mod conflicts with alot of things.

 

Coincidance? I think not...
I have the same mod installed, I'll try it and tell my results today/tomorrow (time zones)

 

I tried it, sadly nothing gets better.
