@ElenaP32276 well.. hate to Burst your bubble but, If what you say is correct then why would it gain fuel? If the engine is running at the same time it would just consume fuel. I see what you mean but here is the explanation in a more nerdy way: In the game files there is the fuel, consumption of ml and then how fast thrusters should drain the fuel. If a value goes below zero then it reverses the effect of that line of code. Under thrusters there is probably a line of code like "fuel consumption speed + 60% If that number goes below zero it becomes a minus number (-20%) It's kinda like the minus world in the original super Mario bros or like when the scooter bug shows -2 million meters. That's my explanation, I might be wrong!
Mastery is the WORST update in history of hcr2. If only bad vehicles would have it would be ok. But naaah we are smart FS so let's add it for every vehicle. This also makes the game even more pay to win that it already was after nitro. If that's how it is going to be i'm gonna quit the game.
