My NPC make Alyx crush game!

[IAmError]

Strange thread name? Yes! I have very strange problem: i can spawn many different NPC's and my NPC and all will be fine, but when i spawn Alyx and she detects my NPC - game crushes. It's very stupid and i don't understand why this happens. It's really happens when Alyx detect NPC, because i spawned my NPC in room with mirror (map gm_construct) and Alyx near player spawn. NPC start running to Alyx and when she detects him...crush. Any ideas why this happen and how to fix this? This is dump file debugged with WinDbg:

Maybe something wrong with class? I watch in vj base and not find npc class. In vj code npc use strings as class (don't fully understand how it work). I just do this:

ENT.m_fMaxYawSpeed = 240
ENT.m_iClass = CLASS_ZOMBIE

AccessorFunc( ENT, "m_iClass", "NPCClass" )
AccessorFunc( ENT, "m_fMaxYawSpeed", "MaxYawSpeed" )

[IAmError]

Very interesting. If i not set npc class and add this in enemy find code in entity "checking":

if(TEMP_NPC:IsNPC()&&string.sub(TEMP_NPC:GetClass(),1,10)!="npc_kfmod_"&&TEMP_NPC:Classify()!=CLASS_ZOMBIE) then
	self:AddEntityRelationship(TEMP_NPC,D_HT,99)
	TEMP_NPC:AddEntityRelationship(self,D_HT,99)
end

npc fight with Alyx and no crushes...wtf?
