Sup , im having troubles with this spell,
its looping a a function and it does work but the problem comes when the player dies and the spell is still there.

can someone help me fix this, or maybe a tip on how to solve it?

Code:
function onTargetTiledmg(cid, pos, creature)
    local player = Player(cid)
    if not cid then return false end
    
    local level = player:getLevel()
    local ml = player:getMagicLevel()
    
    local amin = 1
    local amax = 1
    local damage = {min = -amin, max = -amax}
    
    for i = 1, config12.rounds do
        if not cid then return false end
        addEvent(function()
        if cid then 
            local param = {}
            param.cid = cid
            param.pos = pos
            param.count = 0
            doAreaCombatHealth(cid, COMBAT_HOLYDAMAGE, mainPos, areaxx, 0, 0, config12.ggx1)           
            doAreaCombatHealth(cid, COMBAT_HOLYDAMAGE, mainPos, areaxx, 0, 0, config12.ggx2)                               
            
        end
        end, i * config12.speed)
    end   

end
    
holycombat:setCallback(CALLBACK_PARAM_TARGETTILE, "onTargetTiledmg")
realcombat:setCallback(CALLBACK_PARAM_LEVELMAGICVALUE, "onGetFormulaValues")

function onCastSpell(creature, variant)
    mainPos = creature:getPosition()
    holycombat:execute(creature, variant)
    
    for i = 1, config12.rounds do
        if not creature then return false end
        addEvent(function() if creature then                         
        realcombat:execute(creature, variant)
        end end, i * config12.speed2)
    end
    
    
    return true
end
 
You are passing userdata to addEvent, which dereferences nullptr if creature logs out or die. Pass creature id and recreate userdata using Creature()
