[JASS] strange error

[PrisonLove]

ok so i keep getting an error message when i go to save my game and i dont know why. when i go to enable the trigger it gives me no error message but when i save it does. here's the message i get

and here's my trigger:

function Trig_Charge_Rocket_Conditions takes nothing returns boolean
    return GetSpellAbilityId() == 'A00J'
endfunction

function is_mechanical takes nothing returns boolean
    return ( IsUnitType(GetFilterUnit(), UNIT_TYPE_MECHANICAL) == true )
endfunction

function is_flying takes nothing returns boolean
    return ( IsUnitType(GetFilterUnit(), UNIT_TYPE_FLYING) == true )
endfunction

function unit_type takes nothing returns boolean
    return GetBooleanAnd( is_mechanical(), is_flying() )
endfunction

function kill_unit takes nothing returns nothing
    call KillUnit( GetEnumUnit() )
endfunction

function Trig_Charge_Rocket_Actions takes nothing returns nothing
    local unit caster = GetTriggerUnit()
    local unit TempUnit
    local unit TempUnit2
    local location TempPoint = GetUnitLoc(caster)
    local location TempPoint2 = GetSpellTargetLoc()
    local group TempGroup
    set TempUnit = CreateUnitAtLoc( GetOwningPlayer(caster), 'h005', TempPoint, 270.00 )
    call UnitAddAbility( TempUnit, 'A02H' )
    call UnitApplyTimedLife( TempUnit, 'BTLF', 6.00 )
    set TempUnit2 = CreateUnitAtLoc( GetOwningPlayer(caster), 'h006', TempPoint, 270.00 )
    call UnitAddAbility( TempUnit, 'A02I' )
    call SetUnitAbilityLevelSwapped( 'A02I', TempUnit2, GetUnitAbilityLevelSwapped('A02G', caster) )
    call UnitApplyTimedLife( TempUnit2, 'BTLF', 6.00 )
    call IssueTargetOrder( TempUnit, "acidbomb", TempUnit2 )
    call TriggerSleepAction( ( DistanceBetweenPoints(TempPoint, TempPoint2) / 700.00 ) )
    call IssueImmediateOrder( TempUnit2, "thunderclap" )
    call DestroyEffect( AddSpecialEffectLoc( "Abilities\\Spells\\Human\\Thunderclap\\ThunderClapCaster.mdl", TempPoint2 ) )
    call DestroyEffect( AddSpecialEffectLoc( "Abilities\\Weapons\\Bolt\\BoltImpact.mdl", TempPoint2 ) )
    set TempGroup = GetUnitsInRangeOfLocMatching(300.00, TempPoint2, Condition(function unit_type))
    call ForGroup( TempGroup, function kill_unit )
    call RemoveLocation(TempPoint)
    call RemoveLocation(TempPoint2)
    call DestroyGroup(TempGroup)
    set caster = null
    set TempUnit = null
    set TempUnit2 = null
endfunction

//===========================================================================
function InitTrig_Charge_Rocket takes nothing returns nothing
    set gg_trg_Charge_Rocket = CreateTrigger(  )
    call TriggerRegisterAnyUnitEventBJ( gg_trg_Charge_Rocket, EVENT_PLAYER_UNIT_SPELL_EFFECT )
    call TriggerAddCondition( gg_trg_Charge_Rocket, Condition( function Trig_Charge_Rocket_Conditions ) )
    call TriggerAddAction( gg_trg_Charge_Rocket, function Trig_Charge_Rocket_Actions )
endfunction

does anyone know why this is happening?

the error comes when the map is saving it goes to Generate Map Script Variables

edit: here ill include my GUI version (which i know is not MUI thats why i changed it to JASS for the MUI and the native functions). On the GUI i still use destroy group but i get no error why is this? ive figured out that this error is linked to the groups

Jass code gives me no errors.
I suppose it is some issue connected with macs, but since I am not using one ...
