Works as intended
Not very rare, but can be partially buried under sand.
Was the world single player?
Was the TNT still there?
Not true. The respawned dragon drops less xp, but still some.
The dragon doesn't destroy end stone.
This is so they don't have huge problems with the dragon's hitbox.
According to the wiki, "Zombies spawned within a siege ignore player proximity, light levels, and the presence of other mobs."
According to the Minecraft wiki, "A dispenser can be used, if adjacent to a villager, to place armor on it. While not visible (except pumpkins and mob heads), the equipment functions as normal."
Nitwits.
They can only break doors in hard mode. Is mob griefing on?
Works as intended for all dimensions. That is a locked repeater.
Only in the nether?
Not a bug. There is nothing to prevent that from happening. The player cannot sleep in the Nether because players can only respawn in the overworld.
Watch out when updating gravel "shelves".
Just polar bears?
