When adding this mod to the game, there's an error message:
Failed to load mods: Error in assignID, technology with name 'electric-energy-accumulators-1' does not exist.
Source: accumulator-superior (technology).
Mods to be disabled:
* Selightselectricity

This error can be fixed by editing line 68 of /prototypes/technology.lua in this mod such that instead of:
prerequisites = {"electric-energy-accumulators-1"},
it should read:
prerequisites = {"electric-energy-accumulators"},

This allows the game to be loaded with the mod.
