GetEntityExists looping timer with monster

[FlawlessHappiness]

Good idea!

EDIT: I can't get it to work...

Here is my script.

Spoiler below!

void OnStart()
{
AddEntityCollideCallback("servant_grunt_2", "ScriptArea_10", "OnMonsterCollide_3", true, 1);
}

void OnMonsterCollide_3(string &in asParent, string &in asChild, int alState)
{
AddTimer("IfMonsterCollide", 0.1, "IfMonsterCollide");
}

void IfMonsterCollide(string &in asTimer)
{
if(GetEntitiesCollide("ScriptArea_11", "servant_grunt_2") == false)
{
AddDebugMessage("Level door is unlocked", false);
PlaySoundAtEntity("", "door_level_cellar_open", "Player", 0, false);
SetLevelDoorLocked("level_celler_1", false);
RemoveTimer("ReenableMonsterCollide");
RemoveTimer("IfMonsterCollide");
}
else
AddDebugMessage("Timer_1_active", false);
AddTimer("ReenableMonsterCollide", 0.1, "ReenableMonsterCollide");
}

void ReenableMonsterCollide(string &in asTimer)
{
AddDebugMessage("Timer_2_active", false);
AddTimer("IfMonsterCollide", 0.1, "IfMonsterCollide");
}

The monster disappears, but the timer doesn't get anything...
