After player is being killed by multiple ender crystals a death message will be shown. If player waits for a some time before respawning, player will be moved quickly after respawning causing new death (by falling from a high place). After I closed the world and reopened it I found that i fell from the world.

To reproduce this bug:

1. Create any world.
2. Place command block that summons and explodes ender crystals
3. After switch to survival/adventure mode and go to the towards crystal
4. Wait for 10-20 seconds before clicking "Respawn" button
5. You will be "jumped" away your world.
