I have completed GTA 5 for 35% just completed the 40th mission. After the online update I didn't see any missions except the question marks and the Lester missions. I already did one Lester mission. Don't want to complete the rest because of the stocks change with this mission. I'm waiting untill I almost completed the game so I can invest more money on the stock changes.
Do I need to complete these Lester missions to really continue? Or is there a bug or something that's preventing me to continue?
This could maybe help to the solution. One of the last messages I got with Michel: Collins? needs to receive the JB 700 before anyone gets paid. I googled this, the car looks like to be a James Bond car or something. I have never seen this car in the game. Do I need to steal this somewhere so I can deliver it and continue with the story line?
