When I mine a spawner and it touches the ground, it just instant despawns. This happened to @Dutchflame_ and me twice. Once we mined it, touched the ground and it was gone, our skeleton spawner. The second time I catched the creeper spawner, but when I was throwing it to @Dutchflame_ it despawned instantly. We don't think this should be happening.. Is there something to do about this? Because it is kinda annoying and we just wasted 500k of money..
