This patch is complete crap, and a testament to PD not putting enough time into their game or anywhere near adequate testing.
If they were so concerned about duping in the beginning, they should have put a serial number system on cars among many other options. This is not the first game having a duping problem. Plenty of examples exist of what they could have done to fix the problem instead of punishing people that were legitimately using the gift system.
I'm now out a FGT and probably a Lexus IS F concept I had loaned to a friend for their respective series. On top of that, I never duped. I traded legitimately bought/won cars in an attempt to collect the cars I wanted to have from this game. The only X1's I have are the ones I won...
If PD is so concerned about duping they should properly address it FIRST AND FOREMOST. This patch STILL has not fixed duping! After they PROPERLY address the issue, they should delete everyones garage, then again reward cars won based on the completed races in the save file, remove the credit cap and refund all credits earned in the game.
Just when 1.06 was starting to make me think twice about how I felt about PD, they just pulled the rug out from under millions of legitimate players because they got burnt on a duping issue they epically failed on not only before release but 3 months into the game.
