Friend can't see light emitted by mob

[Fancy_Fox_Pers]

I have a creature that uses the following code to emit light. In multiplayer, my friend can't see the light on her screen. It has happened that it doesn't show up on mine either. The light does function, since it prevents to get hurt by Darkness.

local function lightfn(inst)
    local light = inst.entity:AddLight()
    inst.Light:Enable(true)
    inst.Light:SetFalloff(0.4)
    inst.Light:SetIntensity(.7)
    inst.Light:SetRadius(2.5)
    inst.Light:SetColour(180 / 255, 195 / 255, 150 / 255)
    

    
    return inst
end

Thanks in advance!

So now that I have a dedicated server I can more freely test things out. On a normal server, the lights show up just fine. On a dedicated server, they don't show up but still "function" (Darkness doesn't hit). I have tried using the same code as other mods but I still get the same bug. It shows up on a normal server, but never on a dedicated server.

I am probably just not noticing something in the creature's lua file, so here it is in case it is of any use:

PS: The mod that I used for reference was Steampunk DST, that has creatures that emit light. Is there perhaps another mod I should have a look at?

i dont remember exactly how light works but you could try moving

if master_postinit ~= nil then
    master_postinit(inst)
end

to before this

if not TheWorld.ismastersim then
    return inst
end

so it also does it on the clientside

That fixed it! Thanks!
