1 and 2) The arcade controls basically says that if u hold the brake (down arrow) key for a period of time, it will switch into reverse. Ever since I got 0.4.5.1, the arcade controls box was unchecked and I've always kept it that way. The only gears i use is 1st, 2nd, and reverse. No Drive or Neutral. The problems that I'm having is that not only when I put the truck into 2nd gear (Not on the drive gear), the truck will automatically shift down to 1st gear without the press of the page down button but also when I'm in either 1st or 2nd gear, the truck somehow at random times shifts to neutral without the press of the d button. I tried to shift to neutral with the d button and apparently, the d button does not work. I keep pressing and pressing on it to no effect. In version 37, when I put the truck into 2nd gear, even when braking to a stop, it does not auto shift back to 1st gear. In version 37, never have I seen a truck randomly shift into neutral w/o the press of the d button and BTW the d button did work in 37 to effect. I know that we're just beginning the switch over to the new version but is there a fix to these issues?
Edit: The gearbox mode that I've always used is Automatic Shift (page up, page down for shifting) and when I've tried to re-map the controls, none of the buttons worked to any effect and yes I'm using a keyboard.
