I've been experimenting with the new block components today. One of them being the "minecraft:on_player_destroyed" component. When said block is destroyed, an event plays that triggers a randomizer (Randomizer A in this case to prevent confusion), which picks a few options. When Randomizer A picks the third option (it is set to 100 weight so it is more likely), which is another randomizer (Randomizer B), it picks one of four options, each which "spawn_loot". I used the sheep, chicken, pig, and cow loot table in this case. When in game, destroying the block causes the game to crash half of the time.

Steps to Reproduce:
1. Make an add-on with a custom block with the following code (this is my code):
{
"format_version": "1.16.100",
"minecraft:block": {
"description":

{ "identifier": "wacky:wacky_block" }

,
"components": {
"minecraft:display_name": "wacky:wacky_block",
"minecraft:unit_cube": {},
"minecraft:destroy_time": 0.85,
"minecraft:on_player_destroyed":

{ "event": "lucky_block_break" }

},
"events": {
"lucky_block_break": {
"randomize": [
{
"run_command":

{ "command": [ "setblock ~ ~ ~ diamond_block" ] }

},
{
"run_command":

{ "command": [ "give @p stick 1" ] }

},
{
"run_command":

{ "command": [ "clone ~ ~-10 ~ ~5 ~5 ~5 ~ ~20 ~" ] }

},
{
"randomize": [
{
"spawn_loot":

{ "table": "loot_tables/entities/cow.json" }

},
{
"spawn_loot":

{ "table": "loot_tables/entities/pig.json" }

},
{
"spawn_loot":

{ "table": "loot_tables/entities/sheep.json" }

},
{
"spawn_loot":

{ "table": "loot_tables/entities/chicken.json" }

}
],
"weight": 100
},
{
"run_command":

{ "command": [ "summon slime ~ ~2 ~" ] }

},
{
"run_command":

{ "command": [ "execute @p ~ ~ ~ structure load obsidian_trap ~-1 ~ ~-1" ] }

},
{
"run_command":

{ "command": [ "execute @p ~ ~ ~ structure load lava_pit ~-3 ~-50 ~-3" ] }

}
]
}
}
}
}
2. Destroy the custom block.

Expected Results:
The custom block drops either a cow's, sheep's, pig's, or chicken's death loot table.

Observed Results:
The game crashes. I have tested this three times.

On a side note, the options listed in Randomizer A work perfectly fine (apart from the third one, of course.)
