I've been having longer load times since the patch too, i'm series X, but ive just experienced something bizzare,
I tried to do the seasonal Playground Games, only 3 cars were moving in Infected and I was getting infected right away from invisible cars, then in the Team King game I was spawned on the other side of the map.
I then tried to drive to the area 9km away and got kicked due to inactivity.
It's completely broken.
Edit: Went to buy a car, it's now been stuck on the Saving Content screen for the last 5 minutes, i'm afraid to turn it off
