I Rik! I love your mod and I think it's awesome. I've been using it for like 1 year, the problem is that now, whenever I start my world, this crash happens because of the mod (just about a week ago). I started installing the newer version but it keeps crashing. I made a thread in the minecraft forum and they said it was because of this mod. I love this mod so could you please see what's wrong?

Here is the crash report:
