We had an 8h race yesterday and we encounter this bug 2 times (S397 Porsche GTE on S397 Sebring). Each times, my teammate had damages on the car, select "Repair All" on the hud and assignated me as the next driver. When at the pit, the repair time was correctly noted on his side and he let the repairs going till the end. But when I enter the car, I had still the damages on the car and had to return to the pit one lap later to repair (and this time, with no driver swap, it was correctly done). We've also heard about this same bug for another team in the same race (again during the driver swap). We've lost nearly 10 minutes because of this bug, it's a bit annoying.
