I was able to finally replicate the wrong position bug using the newest version (1.08)! On the Hockenhamring i was on 6th position just behind the 5th placed driver (Hakkinen) when crossing the finish line. Just before the racescreen faded away me and the driver behind me, who i just overtook in the last corner, both gained a position with Hakkinen now in 7th. Maybe he retired just after the race finished, or because all three were within a split second?
I also noticed three other bugs:
1.) When you give an order to your second driver before the race starts, you can't switch him back to normal until the race starts.
2.) It kinda feels like when setting the dev focus on the next years car that development on the current is also elevated.
3.) I had a few instances where i got no sponsor bonus even though i should have. The screenshot below shows the standings after the first race (double points) with me finishing 4 and 7 but not getting the bonus for finishing the race 6th or better.
