[1.11.2] Server Crash Report

[MutedTetris]

I apologize for putting this here, but I have looked everywhere and tried everything to fix this problem that I can think of.
I run a multiplayer modded server for a friend of mine and I, and it was working perfectly fine about a month ago. But now that I've put it back up and tried to get it running, it crashes whenever someone logs on. 
I have tried removing mods, changing the version of forge, and numerous restarts.

Here is the crash report:

Any help would be appreciated, thank you for your time.

It's an issue with Varied Commodities. Update it to the latest version (29oct17), and if the issue persists, report it to the author.
