Like the title says. I looked at the mod Animalz, decided it wasn't my thing, hit the back button. I go into my game and there's ostriches? It didn't show up in the game's mod menu until I did subscribe to it (after I saw ostriches), and when I disabled the mod and later took it out, again, there are still ostriches. They aren't a part of any other mod I use, so far as I can tell, and it certainly doesn't look like the were suddenly added to the unmodded game. Does anybody have any ideas?
