When I set B:use_research_system=false in the main config file, the game crashes before the main menu. This happens even with just AW2 and CodeChickenLib.

EDIT: Also, I did not change any other config options from default.

This is now resolved in the latest release on CF. Also JEI now displays all of these recipes correctly as normal crafting ones.
