One reason for me not already mentioned by others yet is the pileup of redundancies explained at the end: ::: spoiler spoiler for full story Humans fucked up Earth and engineered different solutions/fall back options and they all activate at pretty much the same time, leading to them interfering with each other and destroying the societies that managed to grow after the collapse. :::

That’s just how it works with every wax candle, it’s the physics behind it. Beewax has an even lower melting point than Stearin, so it should happen the same if you put 20 candles next to each other.
The problem is that burning candles release heat. More candles close to each other -> more heat -> faster evaporation of the wax -> faster burning -> even more heat. But it’s not happening from 3 or 6 candles, we are talking 15 or even more.
