[vJASS] Trigger breaks the map

[Opaque]

Hello, I'm having difficulties with a vjass spell that I'm making. The map compiles it fine, without syntax errors, but it makes map unplayable. Any help would be greatly appreciated ^_^

Basically, this spell procs when a unit damages a unit, for that I used Weep's GDD. When the unit takes damage, it has a certain % chance to spawn three illusions that damage it, and if the attack procs from behind, it will spawn a lot of images that push the unit forward. It also uses kenny's Knockback System, and Trollvottel's Unit Fading System to knockback and create the illusions, respectively. I know that these aren't the problem, though, because when I comment out the function calls to these systems, the spell is still broken... and I can't figure out what's wrong

I also used TimerUtils, but I highly doubt that's the problem O-o

Anyways, here's the code:

Yes, I know the conditions are messed up(useless BJs), but I was too lazy to change it when I converted the trigger ^_^ And yes I use PolarProjectionBJ, I really don't want to learn trig functions xD

struct LingeringFront
unit pred
unit predtarg
real lingdmg
endstruct

struct LingeringBack
unit pre
unit pretarg
real lindmg
real linface
endstruct

struct LingBackDmg
unit pr
unit prtarg
real lidmg
endstruct

//yeah didn't clean the messy conditions part up yet.... but i doubt that this is the problem

    if ( not ( GetUnitAbilityLevelSwapped('A02X', udg_UNIT_Heroes[GetConvertedPlayerId(GetOwningPlayer(udg_GDD_DamageSource))]) > 0 ) ) then
        return false
    endif
    if ( not ( GetRandomInt(1, 100) <= ( GetUnitAbilityLevelSwapped('A02X', udg_DamageEventSource) * 2 ) ) ) then

        return true
    endif
    if ( ( AngleBetweenPoints(GetUnitLoc(udg_GDD_DamageSource), GetUnitLoc(udg_GDD_DamagedUnit)) >= ( GetUnitFacing(udg_GDD_DamagedUnit) - 20.00 ) ) ) then
