I'm not sure if any of the normal recipes got changed from what is already here in the mod, but with the addition of the Expensive recipes variant in game it would be nice if there was another version or a toggle for Research Revolution to simulate that.
This is mostly for other programs or mods like Helmod or Foreman that aren't up to date with .15 yet but do still work with .14 stuff. IT would be nice not having to rely on spreadsheets for the moment to figure out the proper ratios.
