Modulescript not running, but regular script to run module runs the full code?

So I've been playing around with module scripts recently and I've tried making a basic sword attack where when the hitbox of the sword connects it tells a module to calculate the damage. This way, I don't have to manually change each and every sword if there needs to be an update in the future.

The issue though is that the touched event I'm running will say that it runs the full code, but the module then will not run, except for only sometimes. Therefore only dealing damage sometimes. The damage patterns appear to be random.

Serverscript (prints "Works" all the time):

local combatScript = require(game.ServerScriptService.combatModule)
local char = script.Parent.Parent.Parent
local plrs = game:GetService("Players")
local plr = plrs:GetPlayerFromCharacter(char)

local alreadyHit = {}

script.Parent.Touched:Connect(function(toucher)
    if toucher.Parent:FindFirstChild("Humanoid") then
        local isThere = table.find(alreadyHit, toucher.Parent)
        if not isThere then
            table.insert(alreadyHit, toucher.Parent)
            combatScript.lightAttack(plr, toucher)
            print("Works")
        end
    end
end)

char:WaitForChild("attacking"):GetPropertyChangedSignal("Value"):Connect(function()
    if char.attacking.Value == false then
        table.clear(alreadyHit)
    end
end)

Module (Prints "will run" only sometimes, but completes the function normally when it does):

function combatHandler.lightAttack(atkPlr, toucher)
    print("Will Run")
    if toucher.Parent:FindFirstChild("Humanoid") and atkPlr.Character.attacking.Value == true then
        local atkChar = atkPlr.Character
        local parried = false
        local char = toucher.Parent
        local plr = plrs:GetPlayerFromCharacter(char)
        --For Players
        if plr then

        else
            --For Doomborne
        end
        --Now damage management
        if char.parrying.Value == true then
            --For the Defending Player
            char.timesParried.Value += 1
            --Focus Calculation
            if char.timesParried.Value > 1 and char.inFocus.Value == false then
                char.focus.Value += 1
                if char.focus.Value >= 5 then
                    char.inFocus.Value = true
                end
            end
            --When Animations are done, add playing them here
        elseif char.Humanoid.Health > 1 then
            print("They're up still")
            local damageCalculation = char.Humanoid.Health - atkPlr.Character:FindFirstChildWhichIsA("Tool").baseDamage.Value
            if damageCalculation < 1 then
                print("Down to 1")
                char.Humanoid.Health = 1
                char.Humanoid.Sit = true --Add Knocked Animation
            else
                char.Humanoid:TakeDamage(atkPlr.Character:FindFirstChildWhichIsA("Tool").baseDamage.Value)
                print("Damage Dealt")
            end
        end
    end
end

Is this a problem with my code? Or is this a bug with module scripts right now?
