So this bricked my entire factory when I updated took me a minute to find out what was going on, I think its a great idea to convert for productivity than more recipes but you released it in the worst way possible, I either have to ignore the update on my mod manager or be forced to loose all the production while I re research everything. I was on tier 6 of every recipe but now I've lost all that research time all those science packs. I have a huge list of stuff to research just to make my factory efficient again with huge cost increases in science packs, I'm dreading it, its going to take forever. Please just make Crafting Efficiency 2 or Crafting Efficiency Space Age with these changes so it doesn't mess up a whole playthrough for 6-8 hours. Then phase out the first mod and keep updating the second. Thank you.
