problem with emmissive material

[ArcaneParadigm]

I'm trying to create a emmissive material and it only works randomly for a second then wont work again

working

so same material - the one with the heavy yellow light is what I would expect
but

all i did was click on the material node and the emmission stopped working and i coulndt get it to work again

I tried blackbody and texture and it 99% doesnt work - only occasionally for a second will it emit

also use arealight as possible as, if you cannot understand the concept.

It came back again but then I clicked on the material again and it stopped emitting light

Also notice I'm using a symmetry object to mirror the poles and lanterns and the glow is only on one side

so the emmission is not being transfered to the other side either
