All on PS4 in Career Mode.
- AI getting stuck in the pits at Bathurst
- Not getting a tyre change while Change Tyres was put to 'yes' in the Pit Strategy menu
- Tuning settings get changed by the game to something completely unusable (happened in the Historic GT5 BMW 320 at Imola. (Especially the gearbox settings were all screwed up)
- Crashed out in last place, leaving me with mechanical damage. I chose to 'skip to end of session' and got 6th place and some good points
(Ginetta Juniors career on Brands Hatch)
- Rendering bug on several tracks where you see striped black lines somewhere in front of the car. It's most noticable on Brands Hatch. And no, it's not the windshield reflection...
- Lapped AI not getting classified a lap down, and stealing the classification of cars in the lead lap. This doesn't always happen though. Most of the time you see them taking the higher positions while still in the race, but then in the end classification it's all ok again. Sometimes they keep their stolen place in the end classification though.
- Overpowered Ginetta GT4 on most tracks in the GT4 Career Mode. On most tracks they're up to 3 seconds a lap quicker than the other cars.
- Already mentioned by others I saw but o so annoying: Unrealistic practice / qualifying times set by the AI and incorrect AI behavior in the wet, on wet tyres in the dry, and on supposedly worn tyres.
