Glitches. One of the most hateful things in Minecraft. I don't get glitches very much, but this one glitch almost broke my account.
I was in a Creative world which I named "Invasion," I spawned thousands of hostile and neutral mobs. And that's when it happened. All the mobs were going crazy. Their rampage went on for half-an-hour. By then, they all disappeared and a storm started. But it wasn't raining rain drops... it was raining mobs! I was so confused. After a while an Enderman fell on me and my game crashed. I checked the error code and this is what it said: Error: Glitch-Storm|||EF%23/downfall=mobs
