This is happening for a while now so it is not specific to this update. There is also a similar bug freezing the loading wheel after an event finishes and force you to wait for a long time…
It’s possible I didn’t notice it before, but I don’t think I had it until this update. I haven’t been playing constantly, but when I do, I’m often leveling cars in Free Play (to tune and race them in open multiplayer). I noticed the load time was way longer as soon as I went to test the proximity radar.
