I can't find any Bug Reporting form so I'm going to have to improvise.
Report Code: ZDGC-CHBR-DKDK-CRKG
Game Mode: Driver Career
Platform: PC (Steam)
Description: 50% race at Bahrain, Season 1. Crossed the line in 20th but was instantly demoted to 21st, with my teammate leapfrogging both me and Alonso, who was in 19th. No penalties, no red flags.
This is identical to a bug that appeared in F1 22.
I have uploaded a video of this issue, keep an eye on the bottom of the finishing order as I cross the line.
