[CRASH] When a player is riding an entity that explodes, the game crashes.

W10 1.6.1.0_RC0 Minecraft - Release_1141430

Summary: Noxcrew's SPACE Creative Toolbox allows players to have "Dog Fights" in Space with the different pilot-able spaceships. To add to the atmosphere, the ships explode when they take fatal damage. They are provided with projectiles that deal damage to other ships. When a player is riding a ship, and that ship takes fatal damage, it tries to explode and the game crashes. The crash does not happen when the entity is not set to explode. The crash does not happen when the ships explode with nobody riding them.

If you remove this:

"minecraft:explode": {
   "fuseLength": 0,
   "fuseLit": true,
   "power": 3,
   "causesFire": false,
   "destroyAffectedByGriefing": true
 }

The game does not crash.

Impact: In this scenario, if a player blows up another ship while it's being piloted, which they're encouraged to do, they'll be rewarded with a hard crash.

Repro Steps:
1. Download Noxcrew's "SPACE" Creative Toolbox from the store.

2. It's easier if you teleport to 4000 10 4000 where there's flat ground to operate on.

3. /summon iron_golem

4. Right Click it to enter. 

5. /effect @e[type=iron_golem] instant_damage 10 0 true

6. Crash

7. Reopen map

8. /summon iron_golem

9. Don't get in. /effect @e[type=iron_golem] instant_damage 10 0 true

10. No Crash.

Observed Results: Crash

Expected Results: No Crash
