Love the mod, it seems to have broken on the 1.1.1 update with a "content configuration validation failed" error. Looking at the database.log, it seems to be a conflict now that Bolivar is in-game, I'm assuming that the memento is now part of the base (DLC) game and so the version you have is no longer unique? If I disable your mod, it loads fine; or, if I disable the official Simon Bolivar additional content, it loads fine.
UNIQUE constraint failed: Types.Type
While executing - 'INSERT INTO Types(Type, Kind) VALUES('ATTACH_BOLIVAR_MOD_FREE_BUILDING_TYPE', 'KIND_MODIFIER')'
ERROR: Failed to add Modifier (ATTACH_BOLIVAR_MOD_FREE_BUILDING)
