No DLC Paint for C70
@GD80 I confirm the same problem. I clearly remember that DLC color scheme was there in 6.0, so it is something brought by 6.3 patch.
All other DLC color schemes (both Khans, Tayga, both DLs, Chevy 1500) and content are there - so it is not a save corruption.
The bug migrated to live 6.0.
They even showed this bug in new promo video exactly at 1:45.
