I'm looking more through the crash log (I can't load the world AT ALL now), and it looks like the problem is with a Draconic Evolution Dissenchanter. I only have one of them in the entire save, and it's located in "The Last Millennium" from ExtraUtils. I've found a possible solution using NBTExplorer (removing the problematic entity), but I can't figure out which DIM ID was assigned to The Last Millennium.

FIrst, does this sound like an effective solution?
Second, does anyone know which DIM ID was assigned to The Last Millennium?
