[SOLVED] Sponge & Pixelmon 4.0.8 Crash

EDIT: Fixed the issue. It was a problem with old libraries and deleting them seemed to fix it.

Recently I have been looking into sponge and have finally decided to give it a go. There is one problem, and that is every time I try to launch my server, the server crashes after starting to load the world (according to console). I have tried using multiple versions of sponge and the corresponding forge version to no avail. Any help would be appreciated.

Current Plugin’s and Mods:
Core (Sponge API Plugin)
Sponge 1530 2.1 DEV-767 (Universal)
Pixelmon 4.0.8

Forge version is (Universal)

FML Server Log
Crash Report

P.S I really love these forums, they are well done and some of the cleanest I have seen in a very long time.

The CoMod error was fixed by a PR that was accepted yesterday, it should be in a 1530 build of forge so update to the latest

Do you know the exact version? As far as I know, I have tried the newest one.
