Crash with 'load Script'

Hello,

I use this mod on my server. Everything works properly (exept one or 2 spawners but that's not the problem) but when i do 'Load scripts', the launcher crashes.

The crash is only for the launcher, not for the server. And it crashes when i am on a soloplayer game and on a multiplayer game.

Here are the logs :

[15:10:23] [Client thread/INFO]: [net.minecraft.client.Minecraft:func_71377_b:349]: ---- Minecraft Crash Report ----

// Don't be sad. I'll do better next time, I promise!
