2 player coop session. Player 1 loaded a truck. Player 2 switches to the truck and truck is fine. When player 1 returns to the same truck, the truck is stuck at gear 1 on Auto.
Same thing happens on PS4 anytime another player gets in my vehicles the truck will not shift out of first gear when I get back in it
Workaround fix is to either zone into a gateway or go to another region's garage then switch back to the truck.
This also fixes the issue when you start lagging because there are things that are glitching in the session.
