Internal Server Error - Ender Chest

[IAmOmicron]

Title: Internal Server Error - Ender Chest

Version: 3.1.2

OS: Windows 7 Ultimate (x64)

Java Version: 1.7.0_09 - Oracle Corp.

Description of Problem:

NOTE: Version 3.1.3 (No option in the bug report as of the current time)

So yeah, spawning an ender chest gives an 'Internal Server Error'.

And crafting one gives an 'End of Stream' error.

Ender Pouch, however does work.

Might a conflict in CodeChickenCore, however i'm also probably wrong.

Error Messages:

Internal Server Error (Spawn)

End of Stream (Craft)

Error Log:

When crafting:



[iNFO] #Player# lost connection: disconnect.genericReason







When spawning one:
