The bug

The spore blossom, despite being a flower, functions very differently from all other blocks called flowers. For example, most flowers are x-shaped and require a supporting block below, whereas spore blossoms are concave and require a supporting block above. Despite this, the spore blossom is placed right in the middle of a row of x-shaped traditional flowers in the Creative inventory.
