Describe the bug
BuildCraft scans every item during post-init for it's guide book, however this crashes when it reaches the "II:Packer" schematic - most likely due to Immersive Intelligence initializing it's multiblocks during post-init as well.

(see BuildCraft/BuildCraft#4664 for the original report)

Environment

• OS: unknown, I assume it doesn't matter?
• Minecraft version: 1.12.2
• Forge version: 14.23.5.2860
• Immersive Intelligence version: 0.2.1
• Immersive Engineering version: 0.12-98

(A full mod list is included with the linked crash report)

Suggested Fix
A hacky fix on your side would be to add before:buildcraftlib; to your @Mod(dependencies) declaration - at least that's probably the simplest solution that doesn't require moving either buildcraft's guide logic or II's init logic.

...I should really check for duplicates before opening an issue.

Sorry!
