As the title suggests, Melons and Pumpkins don't grow instantly when bonemealed in creative. This is a very annoying bug as I'm trying to test build farms in creative for my survival world and unlike every other crop Melons and Pumpkin stems don't grow instantly. This is a smaller bug but can be extremely annoying when trying to build mass farms.
