Bug when changing difficulty of drivatars

I first noticed this bug when FH3 was first released, that when you change difficulty of an event and drivatars are reloaded, you sometimes get duplicate drivatars, and the race points for both drivatars are awarded to one of them, making them almost unbeatable.

Given that it’s such a well known bug, how come it hasn’t been fixed yet?

We still bought the game and did not refund it, so why bother?
