Who is the owner of the lamp in question? We need to punish them.
And do not say Rime, because I light everything with Glowstone or Redstone Lamps, THE WAY NOTCH INTENDED FOR US TO LIGHT THINGS, none of that fancy witchery.
Due to how shitty minecraft's lighting system is, the Arcane Lamp (and many other lamps) utilize randomly scattering false light source blocks that are "invisible". Alot of them. Simply removing the lamp wasn't enough, the child blocks were causing a crash because their parent entity was gone. I've gone through twice now and manually removed a shitload of child source blocks around the general area. I hope to god i've got them all by now...
