The Just Enough Items Integration of EnderIO is not working, because the JEI Plugin is not loading correctly.
It doesn't crash but it's still annoying.
A few days ago it worked fine.

Don't know if it's JEI's fault or EnderIO one's.

• EnderIO: 3.0.1.71_beta
• EnderCore: 0.4.1.40-beta
• Minecraft: 1.10.2
• Forge: 12.18.1.2014
  -JEI: 3.7.7.233

Found this in the log while JEI loaded the plugins:
Full log (too big for pastebin):

Please report this to the authors of the code that is actually crashing first. In this case (ignoring Forge): "alexndr"

Got it, working on it at my end.

Sinhika fixed it with a quick update of SimpleCore
