Car colors are changing?

[NitroNico]

I'm having some strange problems with the cars I buy recently.
I just bought a Ford GT 40, yellow with black stripes.
Suddenly, i see that my car turned all white.
I thought it was just an loading error, but ever since, my Ford GT40 stays completly white.
I noticed that not only my GT 40 but my recently bought Lancer EVO IV(Black), Tuned EVO X(red) and Suzuki Swift Sport(red) colors changed.
The Evo's turned white and the Suzuki turned yellow.

What makes this story strange is that i already bought a red Tuned EVO X but that one didn't change of color.

Why is this happening? How is it possible that the game never gave problems, not even on different PS3's, but now suddenly has appeared en doesn't go away.

I'm playing with the EU-spec (II) and have temporarily no internet-connection on my PS3, so i can't update it either...

The turning white issue has been a rare known bug for quite some time, it relates with Quick tune somehow (personally I think the its a bug where cars are reverting back to base white when tuned, as it forgets what colour the car was bought in) but I havent heard of any switching to other colours like yellow before.

There is already a thread about this problem. I had this issue too, but nothing like that happened since Spec III.

Thanks for the answers so far.

I think the Suzuki turned yellow because that's the first color in line.
If i'm correct, the factory Swift Sport isn't availible in white.(at least in GT5P)

@Red Baron
I couldn't find the thread about this bug, can you give me the URL?
So, updating is the only way to fix this bug?

Do you have the cars quick tune settings on B or C and not A, that seems to change the colours.
