The Problem:
Civilian vehicle gasoline does not change. If you bought a vehicle before this bug, it stays at the same gas level despite if you refilled it and immediately respawned it. If you bought a vehicle after the bug, it will stay on 20/20 and drain when you use it, but like a department vehicles, will be full upon respawn.
Expected Result:
Gas level changing upon respawn if used/refilled.
Reproduction Steps:
drive a car with full gas. watch gas drain. respawn. full gas. get car with less than full tank. refill. respawn. same tank as first respawn.
Pictures/Videos:
Pictures/videos that show the problem and reproduction steps.
Within my time in Firestone as a citizen, I have noticed that you must be inside the vehicle to fill it up, instead of the outside. I am not sure if that helps.
