The other day I was testing the Dinnerbone nametag. I thought that the flipped mobs with regular gravity was 'unrealistic' so i made this datapack, which fixes that issue. Now, when you name a mob Dinnerbone, it flies up, like gravity reversed.
DO NOT DOWNLOAD THIS PACK UNLESS YOU KNOW WHAT YOU ARE DOING. MOBS WITH DINNERBONE WILL FLOAT THE SECOND YOU LOAD A WORLD WITH THIS PACK.
