ents.Create() Problems

[dorfy]

 		local ent = ents.Create('prop_dynamic') 

Any idea why this crashes my server when I attempt this? It used to work for me in an old script I made but now it no longer works. My server doesn't give an error it just crashes and burns into an apocalyptic hell.

Full Code:

		local ent = ents.Create('prop_dynamic')
		print("Printed ent")
		if ((ent:GetClass() == "prop_dynamic") or (ent:GetClass() == "prop_physics")) then
		print("In the conditional")
		ent:SetSolid( SOLID_VPHYSICS )
		print("Set Physics")
		ent:SetMoveType( MOVETYPE_NONE )
		print("SetMoveType")
		end
		ent:SetModel(v.model)
		print("Set Model")
		ent:SetPos(v.pos)
		print("Set Pos")
		ent:SetAngles(v.angle)
		print("Set Angle")
		ent:Spawn()
		print("Spawn")
		
		local entphys = ent:GetPhysicsObject();
		if entphys:IsValid() then
		entphys:EnableGravity(false);
		entphys:Wake();
		end	

It errors out at the entity creation I have already verified that with all those debugging prints and stuff.

FIXED: You apparently can't create a dynamic prop on the map in a function when called by sv_hooks.lua
