Problem with special effects

Hmm i got a really annoying problem with trigger based special effects. I'm making a CTF map, and when an unit picks up the item that is the flag, it makes a speciel effect that is the banner. It all works fine, and i set the variable Blueflag to the effect, but then i want the speciel effect to disappear when a unit dies or drops the flag, and that is where my problem occur.

There is a major delay when the special effect is supposed to be destroyed, and i dont have this problem when using the event:

Event - Unit leaves region

But here i am using:

Event - Unit dies
- A unit loses an item

Condition - Item type of item being manipulated equal to Blue flag

Action - Special effect - Destroy Blueflag
- Hero - drop item carried by dying unit of type Blue flag from
Dying unit

And as i mentioned there is a major delay of about 2 seconds before the flag special effect disappear above the head of the dying unit/the unit manipulating item.

Anyone knows what causes this ? Thanks
