Anmerkung von joshwhedon:

The reason is fairly simple, it is due to _IsValidAttackTarget never being checked for TARGET_CHECK_ENTRY in
bool WorldObjectSpellTargetCheck::operator()(WorldObject* target)
But adding a check for it is not as simple, as it will end up screwing up a lot of spells which are supposed to hit untargettable targets.

Just one addition: using _IsValidAttackTarget is a bad idea (the place is correct however). I tried it and it broke other things. So the check should probably be slightly different (even if the location should be the same).
