Particle Effects not firing in Multiplayer

[Feihc]

For some reason, the ParticleEffect's in my SENT don't appear all the time in Mulitplayer.
In singleplayer everything works fine, but in multiplayer they'll work maybe 1 out of 20 times.

In Init:

ParticleEffect("larvae_glow_extract_b", self:GetPos(), Angle(0,0,0), self)
ParticleEffect("cingularity", self:GetPos(), Angle(0,0,0), self)
ParticleEffect("vortigaunt_charge_token", self:GetPos(), Angle(0,0,0), self)

function ENT:Think()
if self.spawnTime + 1.9 <= CurTime() then
ParticleEffectAttach("warp_shield_impact", PATTACH_ABSORIGIN, self, 0)
ParticleEffectAttach("aurora_shockwave_debris", PATTACH_ABSORIGIN, self, 0)
ParticleEffectAttach("aurora_shockwave_ring", PATTACH_ABSORIGIN, self, 0)
end
self:NextThink(CurTime() + .01)
return true
end

I've precached all the Particle systems, but that didn't seem to do anything.

Is this just a problem with client/sever interactions or something?

Try creating the particles on the client rather than the server.
