Environment

• OS: Linux Debian 10
• Minecraft version: 1.12.2
• Forge version: 14.23.5.2847
• Immersive Intelligence version: 0.1.1
• Immersive Engineering version: 0.12-89
  No other mods installed.

That is a counter for how many items have been created using the scheme (now how many it creates, that's part of "Used to create: something x quantity"). Originally I planned a research system for better components, scraped the idea, but left a counter of created items.
