Anything I recipe check crashes me, ChickenBones wants me to inform you about this problem.
Link to the issue I posted in NEI's issues:
Chicken-Bones/NotEnoughItems#303 (comment)
For now, I guess I will downgrade to a "Recipe Checkable" Mariculture version.

Would have been helfpul if you'd told me the version you were using but either way. 1.7 is done, and JEI for the future \o/.
