This doesn't work. In his case it'll still be raining. This stupid glitch cost me 18 hours of my life that I'll never get back. I suspended at hour 18 with rainy weather and came back sunny. I then proceeded to try suspending and resetting the PS3 and no matter what, it was ALWAYS sunny. I was counting on the rain because I was in a stock Schulze GT-R hanging on to first by 6 minutes against a lightning-fast Pescarolo-Judd. He passed me halfway on our 2nd lap after resuming the race as if I was only 5 seconds ahead
Anyways OP my advice is to just keep doing the race if you think you have a chance of winning. I can't really explain why this glitch is here but it needs to be fixed.
