My car ai is driving after an engine failure but won't retire the car

Writing this as it's going on, currently lap 12 of the Brazilian GP and i had an engine failure on lap 8, it so happened that there was a red flag on lap 8 as the ai was retiring the car. The game went into the strategy menu instead of giving me the terminal damage screen. When I restarted the race, the ai drove for a solid few laps until lap 13 when it gave me the terminal damage screen while he was still driving as normal. The funny thing was that the ai overtook 2 cars before the game forced me to retire fully lol.
