damn one of the forza rewards for Horizon 4 is 50 car masteries
I pretty much 100% all of the others now as they're easy but that one is going to take forever, maybe never.
I have 1 car fully maxed so far and another 3-4 almost done.
Talking of the vehicle skills, I came across a bug last night. I had 16/25 of the points needed to get the last skill for my Honda NSX. I switched to a lambo during a jump challenge and the car had 16 skills points to spend which I thought was a bit odd. I ploughed them all in to the car and it obviously turns out somehow the game carried my Honda points across. Good because I've nearly maxed out the Lamborghini now, bad because that Honda takes forever to get a skill point and now I am back to 0/25 needed
I'm going to try and replicate the glitch so I can use my lambo skill points on other cars as that car has a good skill set to farm points
