Week 4 Sunday Day bug

Product: Need for Speed: Unbound
Platform:PC
Summarize your bug There's uncertainty when it comes to Week 4 Sunday Day - in day challenges you have a "Rescue the racer in trouble" challenge that cannot be completed due to a bug or a developer's oversight - during Sunday you are meant to have a Racer SOS event with Waru. But he never calls you and instead you end up meeting Yaz at Rydell's Rydes.
How often does the bug occur? Every time (100%)
Steps: How can we find the bug ourselves? Finish the 3rd qualifier, start sunday day, open day challenges - find the aforementioned challenge. Cruise around, do some race events, hope Waru will call you for help - but he won't.
What happens when the bug occurs? More like how do I know that? Digging through in-game files led to this knowledge devs don't want you to know.
What do you expect to see? Either restoration of the aforementioned event or absence of the distracting challenge.

And Volume 3 when?
