Disabling Friend of the Night indoors?

[Aklis]

I gave this a shot on my own but I didn't have any luck, so if anyone has any ideas I would be most grateful. I've been working with the FriendoftheNightQuestScript found in the Realistic Wasteland Lighting plugin which looks a bit different from the vanilla version:

scn FriendOfTheNightQuestScript

short bFOTNNightInEffect
; toggle for when FOTN is in effect.  1 = yes.

short bFOTNInteriorInEffect
; toggle for when FOTN is in effect.  1 = yes.

Begin GameMode

    ; JSH 8/11 Don't do effects if the end slide show is in progress
    if Player.HasPerk FriendOfTheNight == 0
        RemoveImageSpaceModifier FriendOfTheNightISFX
        RemoveImageSpaceModifier FriendOfTheNightInteriorISFX
        StopQuest FriendOfTheNightQuest
        return
    elseif player.GetInCell Endgame || (GetPlayerControlsDisabled 1 0 0 0 0 0 0 && GetPlayerControlsDisabled 0 0 0 0 0 1 0) ;//== Movement and hud disabled, almost always means its a slideshow
        RemoveImageSpaceModifier FriendOfTheNightISFX
        RemoveImageSpaceModifier FriendOfTheNightInteriorISFX
        return
    endif

    If Player.IsInInterior == 1
        set bFOTNNightInEffect to 0
        set bFOTNInteriorInEffect to 1
        If IsImageSpaceActive FriendOfTheNightISFX == 1
            RemoveImageSpaceModifier FriendOfTheNightISFX
        Endif
        If IsImageSpaceActive FriendOfTheNightInteriorISFX == 0
            ApplyImageSpaceModifier FriendOfTheNightInteriorISFX
        Endif
    Elseif (GetCurrentTime >= 21.15 || GetCurrentTime <= 5.15)
        set bFOTNNightInEffect to 1
        set bFOTNInteriorInEffect to 0
        If IsImageSpaceActive FriendOfTheNightInteriorISFX == 1
            RemoveImageSpaceModifier FriendOfTheNightInteriorISFX
        Endif
        If IsImageSpaceActive FriendOfTheNightISFX == 0
            ApplyImageSpaceModifier FriendOfTheNightISFX
        Endif
    Else
        If bFOTNNightInEffect == 1
            RemoveImageSpaceModifier FriendOfTheNightISFX
            set bFOTNNightInEffect to 0
        Endif
        If bFOTNInteriorInEffect == 1
            RemoveImageSpaceModifier FriendOfTheNightInteriorISFX
            set bFOTNInteriorInEffect to 0
        Endif
    Endif

End
