Grid uses a mod named cotton-client-commands to parse commands client-side, and it includes version 0.2.1 of that mod itself. Recently, cotton-client-commands updated to 0.3.0, and if you're using a different mod that requires 0.3.0, Grid won't load.

This version fixes that problem, but it *requires* that you either have a different mod that includes ccc 0.3.0, or download and install ccc 0.3.0 yourself. Unfortunately, at the time of this writing, the ccc 0.3.0 download is broken (there is a jar file but it doesn't work correctly).

So only use this version if you have a working ccc mod from somewhere else.
