There is one problem when you put a tower the people in it have like a 1/10 chance of hitting something and when they shoot 1/2 the time they shoot the tower they are sitting in. So I cant trust them by themselves because they almost never hit their target and cant hit thing up close.
The person with 4 girls in the bus when you complete the quest the girls wont get in the car(not sure if they cant) And the guy who gives the quest suddenly disappears and then suddenly when you reload the game he is there and it says take me to your camp with the 4 girls back in the bus but you cant bring him anywhere he is just stuck there.
Last glitch by the bus sometimes if you get out of your car you can glitch under the ramp to the town from the highway
