Hello,
I seem to be experiencing a recurring issue with engines failing/catching fire (my two first IVAO flights with this Aircraft in a row now after a few flights locally with absolutely no problems) - for now I will attribute this to my inability to properly operate the aircraft.
That being said this is also the second time I have experienced the same somewhat annoying bug, specifically, the repro is :
Right engine fire
Pull the right engine fire handle
Causes the Gizmo log to print out the following error : error: 2218.238: RunLuaFunction(xp): main: [string "JGX.1.Saab.00.lua.aes"]:8357: dref.setInt: Expected two arguments.
Following this, power levers & conditioner levers remain stuck in place & become unresponsive to either the Joystick input, Keyboard and/or mouse
The remaining engine cannot be turned off & will keep delivering the same amount of power that was showing on the dials at the time of pulling the lever.
I was thankfully able to turn back to the airport (this was shortly after take off at 2500ft AGL in the initial climb), land & slam the brakes to kill off the 185kt of thrust still produced by the left engine which I was not able to power down and/or turn off.
