[Resolved] Tool existence check causes yielding in the script without error?

I'm working on a script that gives items to the player when an enemy is killed. It also can give items at a chance such as having a 10% chance to get a legendary sword. Here's how I organize the loot table for my mobs.

local _C = {

DropsWeapon = {
		true, {"Blizzard Striker", {1, 1}}, --Format is DoesItDropAnything?, {WeapoName, {Chances of dropping}}
		{"Glaciersteel Cleaver", {3, 10}},
		
	}

}

return _C

Here is the item drop script.

local MobConfig = require(script.Parent.MobConfig)
local Mob = script.Parent
local Enemy = Mob.Enemy

function DropItem()
	if (Mob == nil) or (Enemy == nil) then return end
	if (not Enemy:FindFirstChild("Player_Tag")) then return end
	local Tag = Enemy:FindFirstChild("Player_Tag")
	if (not Tag) and (not Tag.Value) then return end
	local plr = Tag.Value
	local BP = plr.Backpack
	local SG = plr.StarterGear
	for i, v in pairs(MobConfig.DropsWeapon) do
		print("Loop Started")
		if v ~= true then
		if MobConfig.WeaponDirectory:FindFirstChild(MobConfig.DropsWeapon[i][1]) then
			local DropChance = Random.new():NextInteger(MobConfig.DropsWeapon[i][2][1], MobConfig.DropsWeapon[i][2][2])
			if MobConfig.DropsWeapon[i][2][1] == DropChance then
			print("Drop Chance Check")
			print(MobConfig.DropsWeapon[i][1])
			if SG then
				if not SG:FindFirstChild(MobConfig.DropsWeapon[i][1]) and not BP:FindFirstChild(MobConfig.DropsWeapon[i][1]) then
				print("SG Check")
				local W1 = MobConfig.WeaponDirectory[MobConfig.DropsWeapon[i][1]]:Clone()
				local W2 = MobConfig.WeaponDirectory[MobConfig.DropsWeapon[i][1]]:Clone()
				W1.Parent = SG
				W2.Parent = BP
				print("Items Given")
						end
					end
				end
			end
		end
	end
end

if MobConfig.DropsWeapon[1] == true then
	print("Checked for a drop")
	Enemy.Died:Connect(DropItem)
end

The issue is line 22 doesn't seem to check for the weapons' existence. There aren't any errors but I never see "Items Given" in the output.

The issue was I forgot to add a check for the existence of the player's Backpack on line 21. I should've went with:

if SG and BP then

instead of

if SG then

on line 21.
