When real spiceblooms explode, they spawn an invisible spicebloom.spawnpoint actor, which only 'grows' when the cell is of GrowthTerrainType. When 'exploding', it then displays the animation of blowing spice up into the air, and spawns a real spicebloom. This replicates the original behavior where spice blooms would only grow on sand cells that had been harvested and free of spice.
