In-game already have coziness at max (level 5), but achievement and other stuff like mutations have not been unlocked for me, and my friend with whom I share the "backyard / save file" (I'm the owner of the file) got the achievement, the mutation and recipes, therefore, I have access only for the recipes thanks that he got the max coziness stuff, but only that, no mutations nor achievement for me. What is required for me to get this working? (this is my last missing achievement/mutation of the game so far ).
