Just a mod re-install.
The leader-board came up "no leader-board found" before, but it just worked then.
Still, camber extravaganza still doesn't recognize the car.
I thought CM exported the relevant data to solve this.
Although I did see an update for a car that exported a zero as a divisible variable.
To fix camber extravaganza for Supercars:
1. go into "assettocorsa > apps > python > camber-extravaganza > tyre_data folder
2. open v8sc in notepad
3. Replace all "H" tyres with "s"
4. Replace all "S" tyres with "ss"
5. delete file "added-by-cm"
I've attached updated file below.
