What? Win?

i'm used custom core - imagicalmine.

Isnt this the error...
Just remove "->getPlayer()" after "$e->getDamager()" on line 180 and "->getPlayer()" after
$cause = $e->getEntity() on line 181

PHP:

$damager = $e->getDamager();//FIX

What is error? It means the state or condition of being wrong in conduct or judgment.

@wolfdale say it first...
