Graphics glitch looks like drowned truck, at the Smithville dam map near the SOLID FOUNDATION house start point .
Looks like it might be the background graphics out of alignment or the sky box?
I've taken a trip over there myself and confirmed this is also the case for me. Once you drive through the 'water' and out the other side you can't see the glitch but drive back up the hill and it presents itself again.
@SG_Hawk Thanks for the confirmation, already had 2 other people who were playing on my game confirm it separately on theirs as well so it is obviously a coding mistake not a graphics glitch
