I don't know if anyone still supports this mod, but...
When attempting to load game with this mod, this error messages comes up:
Failed to load mods: RealisticFusionPowerPort/prototypes/entities.lua:62: attempt to index field 'horizontal_animation' (a nil value)
stack traceback:
RealisticFusionPowerPort/prototypes/entities.lua:62: in main chunk
[C]: in function 'require'
RealisticFusionPowerPort/data.lua:29: in main chunk
Too bad I am not a modder, otherwise I would post a fix.
