OK, the last four aren't bugs, perhaps.
But I'd really like to know how you've not come across something as common as the tyre wear/fuel depletion pit bug... I guess if you don't take part in the longer races then you've probably not taken a pit stop - fair enough. But GTP, and the wider GT community, sometimes do race in slightly longer races which do require a pit stop to be made. In fact, a lot of the leagues and clubs that feature here on GTP organise and take part in races exceeding an hour in length. It's likely that during these races a pit stop must be made and it's at this point that you'll notice your tyres wearing a lot more than they did before the stop, your fuel depleting at a faster rate than before your stop, and the wear being reversed from the way it was before the stop.
This is the case in both online and offline mode so it's unclear how you've not come across this, as pit stops are required in some of the longer races in A-Spec mode, too e.g. the 15 Laps of Brands Hatch and the 24 Minutes of Le Mans. But these are Super License races and perhaps it's just the case that you've not played this portion of the game just yet, which would explain why you've yet to come across these bugs.
Apologies for accusing you of trolling, but it did seem that way, as it's hard to believe that somebody would not have experienced the very common pit bug.
More bugs I've noticed - if they can be called that:
- on the first long straight on Mount Panorama, if you look behind you, you can see all sorts of graphical glitches happening on the fenced area directly behind you (I do believe this is true of quite a lot of fenced areas on tracks throughout the game);
- sometimes, when exiting the pits at Nurb GP/F, the screen will remain black for a few seconds whilst the car makes its way onto the track, resulting in possible contact with other cars;
- continued replay display issues when changing from one car to another (even though this was apparently ironed out in an update);
- some shadowed reflections on cars appear to be very jagged;
- during the 15 Laps of Brands race in the Super License portion of the game, during the pre race replay camera, the view is very buggy and it appears as though there is a large drop in frame rate, temporarily;
And this is one is potentially damaging to your PS3 system:
- multiple screen freezes, which result in the user having to power off the console, only to be presented with the Hard Drive restore function once the power is restored.
