I've been working on a semi-private modpack based around your mod mainly, plus Hardcore Questing Mode, and I found this crash with Minestuck 104 upon loading a new world:

Also, do you plan on doing anything with the consorts? It seems kind of weird for them to be walking around on their own.

Is the problem only occurring when you're using Minestuck? And if so, what minecraft and forge version are you using?

It happened as soon as I installed 104. I might try 105 however.

105 fixed this issue.
