Really easy to upgrade this one.

Add to data-updates.lua to fix the steam temperature limit:

if data.raw.fluid["steam"] then
  data.raw.fluid["steam"].max_temperature = 800
end

And then go through all the prototypes and swap the category = "blah" to categories = {"blah"}

EDIT: the sprites for the turbines don't wanna load as well, I've not looked into how to fix it yet and might not since my use of this mod has them shoved into Factorissimo buildings out of sight (and out of mind).
EDIT: There also might be another thing broken, if Flow Configuration blocks off a connection into the Steam Converter there's a crash. Might be on Flow Config's end, didn't check
