When I spent the basic game with a friend, I did not unlock an NPC by playing in only their world, how we liked the game, we used this mod and over time I decided to remove it to go to my game without mods and unlock the NPC that did not I unlocked, but since I did that, the mod does not work, the game simply closes when I install it again, while it works with full normality when I remove Frackin´ Universe again
