Aphotic Shield needs some fixes...

[Dinodin]

I have problem with the "Aphotic Shield" ability I imported into my map because it sometimes happening after about 10 mins of gameplay that the ability isn't working at all, it creates the special sfx-shield on the target but it doesn't absorb any damage anymore or dealing it's absorbed damage to enemies and the special sfx-sheild isn't removed either. Also I want it to NOT damage structures and magic immunity units when it is destroyed. Could some helpful soul fix this?
