Sorry guys, next hotfix on its way. This should finally tone down the curbs. If you're racing without curb effects, this update isn't gonna change anything for you -- no need to download again!
And I'm aware it's a pain in the attic to have the hotfixes coming in piece by piece, but apparently my personal quality control didn't really work all that well this time around. Just trying to keep everyone happy as soon as I know there's an issue. My appologies, and thank you for your understanding.
