The problem with modded nefs-files for cars is, that when you use such a car for a community event your times won't be uploaded to the leaderboards!!!!!
Did the weekly Group B challenge with the edited Audi Quattro yesterday and my times weren't uploaded.
I started the monthly challenge and chose the Renault R5, did the first stage with the original nefs-file and everything was ok, my time was uploaded to the leaderboard. Then I quit the game and changed to r5t.nefs and started the game to continue with stage 2. My times wasn't put on th eleaderboards. So I quit the game again, changed the nefs back to the original and started D4. There was no time for stage 2 and I could do it again. This time my time was uploaded to the leaderboards... This also happened to someone else...
Seems the game recognizes when the nefs-file has been edited and blocks the upload of stage times!!!!
Hopefully it won't be in the clubs...or we have to find a solution!
