Not sure who's issue this actually is, but there are certain items which will cause a crash to desktop when they attempt to render using JEI. Posting this here because a line refers to Bookshelf.

net.darkhax.bookshelf.client.render.item.RenderItemWrapper.func_184391_a(RenderItemWrapper.java:303)

JEI, Bookshelf, Thermal Expansion, and CodeChickenLib are all referenced in the log attached, however as I do not know which mod is actually causing this, I am posting this at each mod's GitHub issue section.

Thanks!

It's likely neither. Code Chicken Lib and Bookshelf don't mess with the call unless it is an item from our mods.

Great, I appreciate the quick feedback! Just trying to sort this out. Thanks for all your hard work in the modding community!
