Game crashes at 'data' Thread - CK2: Middle Earth Project (CK2:MEP) mod for Crusader Kings II

This is a full conversion Tolkien mod for Crusader Kings 2 which will feature bookmarks throughout the Third Age. This mod is being developed independently from any other LotR or Middle Earth mods out there. The map will cover the main areas of Middle Earth, known in the books and films. So, Middle-Earth is waiting for you! Will you play as the descendant of one of the noble families of Rohan or Gondor? Will you try to reforge the ancient kingdoms of Elves in Eriador? Or will you try to destroy all the Free Peoples, and claim Middle Earth for Morgoth? This mod will give you a unique strategy experience of the Third Age in Middle-Earth. From Forodwaith to Bellakar, from Lindon to Rhûn, lead your dynasty and survive the Dark Times. Become one of the most important Lords of the Age!
