EvenMoreLights exists because I can be very slow updating my version.
I don't actively play Factorio much any more. So sometimes I fail to notice a major update being released.
Originally when I failed to update the mod for Factorio 0.17, lovely_santa created their version so players could still use it.
Similarly now, I just spotted that 1.1.19 had been released, but failed to notice that 1.1.0 was released 2 months ago.
I suppose by rights, I should just deprecate my mod and let lovely_santa keep the sole version of it up to date (they're obviously tracking Factorio releases better than I am). But partly ego and partly the knowledge that some people still use my version only means I update it where I can.
