Hodir(Cata problem)

In the 25-man somehow enters the fray, one has only to appear in his room and evade also comes into the fight after I summon friendly NPCs (hodir helper npc).
Problem only in 25-man mode, in 10-man mode all fine.
P.S:
Additional for evade bug:
In the battle list the command .combat stop, Hodir will return to spawn point and immediately enter into a fight with you. To playback bug.
P.S:
Seems to me that hodir helper somehow manages to strike at spawn ice flash. Need reaction setreactstate REACT_PASSIVE for all NPC, and when they lose that aura immediately be changed to aggressive.
NPC after themselves must break blocks to help liberate other NPC, but the current EventAI can not.

I think add new ACTION_DISABLE_ATTACK_START and from Hodir side send ai event around on event complete. This is allow complete problem. But my patch not compiling, because not have class AttackStart.
