Repeat until loop being skipped. Please help?

I'm making a tycoon with AI miners that will go mine ores for the player. I have a Union with two values (Hits, OreValue) and two parts (MinePart, Low / Medium / High) I've made a script that whenever an NPC touches an ore, it goes to a position and plays an animation. I have two problems with this code. 1. I don't know how to orient the humanoid to face the ore when mining it. 2. The script ignores some of the lines of code. Here's the code:

-- Low, Medium or High refers to the ore's quality
-- Script does the repeat until loop once sometimes, and doesn't make sure the character is not a player
local blocks = workspace:WaitForChild('Blocks') -- The folder containing all mine-able ores
local anim = script.Animation
local deb = true

function getRandomChild(model)
	local children = model:GetChildren()
	local child = children[math.random(1, #children)]
	return child
end

for i,v in pairs(blocks:GetChildren()) do
	if v:FindFirstChild('OreValue') and v:FindFirstChild('Hits') and v:FindFirstChild('MinePart') then
		v.Touched:Connect(function(hit)
			if hit.Parent:FindFirstChild('Humanoid') and deb == true and not game.Players:FindFirstChild(hit.Parent.Name) and v:FindFirstChild('Low') or v:FindFirstChild('Medium') or v:FindFirstChild('High') and hit:IsA('MeshPart') then
				deb = false
				local loadedAnim = hit.Parent.Humanoid:LoadAnimation(anim)
				local hits = v.Hits
				local regHitsValue = hits.Value -- Original hits value, this is here to make sure that the hits value can return to its original value when the ore finishes being mined
				
				hit.Parent:MoveTo(v.MinePart.Position) -- Moves the character to the MinePart, doesn't orient the character
				wait(.1)
				hit.Parent['HumanoidRootPart'].Anchored = true -- Makes sure that the character stays in one place for the animation
				
				repeat
					loadedAnim:Play()
					wait(loadedAnim.Length)
					hits.Value = hits.Value - 1
				until hits.Value <= 0
				
				loadedAnim:Stop()
				hit.Parent['HumanoidRootPart'].Anchored = false
				hits.Value = regHitsValue
				if v:FindFirstChild('Low') then
					v.Low:Destroy()
				elseif v:FindFirstChild('Medium') then
					v.Medium:Destroy()
				elseif v:FindFirstChild('High') then
					v.High:Destroy()
				end
				deb = true
			end
		end)
	end
end
