MAS Completely freezing

[DeputyLOL]

This has kept happening since i reinstalled KSP. Everything is normal and then the game freezes for about 5 seconds. When it comes back, MAS is frozen completely. Monitors are stuck, alarms don't play or don't stop playing. When i try and hit a MASswitch, I get an initialization error and the log spams with: [ERR 00:08:43.975] [MASFlightComputer] MASFlightComputer.FixedUpdate exception: System.NullReferenceException: Object reference not set to an instance of an object at AvionicsSystems.MASFlightComputer+Variable.ProcessObject (System.Object value) [0x00000] in :0 at AvionicsSystems.MASFlightComputer+Variable.Evaluate (MoonSharp.Interpreter.Script script) [0x00000] in :0 at AvionicsSystems.MASFlightComputer.FixedUpdate () [0x00000] in :0

Reloading the ship seems to fix it.

Just thought i'd let you know :D

I haven't had any hangs or errors. There may be something particular about your installation (a mod or something else that isn't playing nice). A full log file may provide some insight. I've also updated the DLL to provide some finer-grained messages on the ProcessObject exception.

I suspect one of my scripts is causing the problem.

I might have narrowed it down to the GPWS system. Im not entirely sure whats wrong with it though. Here it is:

function ACGPWSOn()
    if ACAltitudeTerrainFeet() < 2500 then -- and fc.GetPersistent("ACGPWSON") == 1 then
        return 1
    else
        return 0
    end
end

function ACGPWSDecending()
    if ACAltitudeTerrainRateFeetPerMin() < 0 or ACVerticalSpeedFeetPerMin() < 0 then
        return 1
    else
        return 0
    end
end
-- GPWS "PULL UP"

function ACGPWSPullUp()
    if ACGPWSSinkRate() == 2 or ACGPWSTerrain() == 2 then
        return 1 -- PULL UP
    else
        return 0
    end
end

-- GPWS MODE 1 "SINK RATE" / "PULL UP"

function ACGPWSSinkRate()
    local ACGPWSSinkRateWarningThreshold = fc.Remap(ACAltitudeTerrainFeet(),0,2500,-1000,-3000)
    local ACGPWSSinkRateAlertThreshold = fc.Remap(ACAltitudeTerrainFeet(),0,2500,-1500,-8000)
    if ACVerticalSpeedFeetPerMin() < ACGPWSSinkRateWarningThreshold and ACVerticalSpeedFeetPerMin() > ACGPWSSinkRateAlertThreshold and ACGPWSTerrain() == 0 and ACGPWSTooLow() == 0 and ACGPWSOn() == 1 then
        return 1 -- SINK RATE
    elseif ACVerticalSpeedFeetPerMin() < ACGPWSSinkRateAlertThreshold and ACGPWSOn() == 1 then
        return 2 -- PULL UP
    else
        return 0
    end
end

-- GPWS MODE 2 "TERRAIN TERRAIN" / "TERRAIN" / "PULL UP"

function ACGPWSTerrain()
    local ACGPWSTerrainClosureRate = ACVerticalSpeedFeetPerMin() - ACAltitudeTerrainRateFeetPerMin()
    local ACGPWSTerrainWarningThreshold = fc.Remap(ACAltitudeTerrainFeet(),0,2000,1800,4000)
    local ACGPWSTerrainAlertThreshold = fc.Remap(ACAltitudeTerrainFeet(),0,1500,2000,3800)
    if ACGPWSTerrainClosureRate > ACGPWSTerrainWarningThreshold and ACGPWSTerrainClosureRate < ACGPWSTerrainAlertThreshold and ACGPWSOn() == 1 then

    else

end

I'm going to punt on this for now - if it's happening with the current dev builds of MAS and KSP 1.3.0, please let me know.
