I was when this started happening. then I switched back to a different game save where I wasn't in the car, I then modded it in the Tuning Shop, painted it in GT Auto, then switched cars, saved the game, and edited that game save. And its still reverting all my weight reduction and engine stages 1, 2, 3 all back to stock, if you know what I mean. That led me to believe it's something to do with the file system on my PS3, and not the program itself. I have tried a few ways that I could think to fix it, and none have worked yet. It's doing this with all my game saves.
How do I get the 4wd layout, transmission and LSD swap to stick to a FF car? Are there any codes that have to be switched as well?
