All other mods work fine but when I try to use iChunUtil for your mods the game crashes at start up. I've uninstalled every other mod and just installed iChunUtil and it still crashes. Everything is at version 1.10.2. Here's the crash report:

This is a Minecraft Forge issue. I'll pass the issue on to them.

In the meantime you should update Forge, iChunUtil requires a higher version of Forge and it's trying to tell you that but it's crashing when it does.
