As of version 0.2.13 pressing the E key to open the inventory crashes the game with a "Unexpected error", while opening the GUIs of other containers like chests and furnaces works (in my case specifficly using HEI) the item search bar as well as item list on the right no longer shows up as well as the machine itself refusing to process any recipes.
This is the fermium crash log: crash.log

For me it was happening for both HEI and JEI.

0.2.13 is for latest hei,it doesn't compatible with jei

Well I'm using HEI, not JEI.

Got this crash today when pressing E after updating to latest version of JEI Utilities

Can confirm the same issue using JEI. Why not make it compatible with both?

HEI recently had an update that seems to work with JEI-U 0.2.13.
