So been playing for a couple of hours now and everything has been fine, except I've now come across a problem with the AI cop cars, EMS, coroners, prisoner transports and pickup trucks randomly braking and speeding up in a consistent pattern. they would speed up to maybe 20kmph and then brake until they stopped and then they would speed back up to 20, and then stop again. It goes on forever. I have no idea why. Everything was absolutely fine with my exact current mod configuration before and I can't seem to solve this problem. It has been going consistent for 20 minutes. I cannot for the life of me figure out which mod is causing this.
Thanks.
