Affects Version/s: Minecraft 16w40a, Minecraft 16w41a
Fix Version/s: None
When I use the /fill Command to turn a region containing Mob Spawners into another block such as Air or Cobblestone, the Particles continue to be emitted by the Spawner even though it is no longer there!
What I expected to happen was:
The Particles fade out, and that becomes the end of that.
What actually happened was:
The particles linger until I rejoin the world.
At some point all of the blocks in the attached image contained a Mob Spawner.
