the Ferrari F430 engine sound goes off on the 2nd race only in championships :
-first take the F430 through a race, her engine sound is fine
-2nd take the F430 through a 2nd race, no more engine sound at all, makes for very silent races lol, you hear gear switching & the brakes and of course the radio if there's any, and other cars engines, as well as ambiant
restarting TDU2 fixes it, the F430 is the only car I own that does this, no other modded or original car does this.
taking the F430 then another car on a 2nd race doesn't trigger the issue.
no amount of restarting a race fixes it, only tried offline but with any race.
edit: only happens in championships, exiting the championshit to take a mission resets the "counter", you have to play 2 championship races in a row with the F430 for the issue to happen
