Hi,
I didn't feel like finishing the mission where you have to kill Yuma. I restarted it and just left the location of the quest. Since I have done so my ammo doesn't decrease. It empties the magazine whilst shooting as it should be but when you change the mag the amount of ammo stays the same. I pretty much have a infinite ammo cheat going on.
Obviously a thing I do not like since it doesn't force you to be creative using yer ammo.
I restarted my PS but it is still going on.
