.CharacterAdded Run on specific lines?

I found this error where .CharacterAdded only runs in certain code lines..

Script Before:

game.Players.PlayerAdded:connect(function(plr)

    local key = plr.UserId

        -- WANT DATASTORE IF STATEMENT HERE. BUT CHARACTERADDED DOESNT RUN.
    if DataStore:GetAsync(key) == nil then
            --// New player data;
            PlayerData[plr] = Default_Data 
            print(HttpService:JSONEncode(PlayerData[plr]))
        else
            --// Current Player Data; Wrapping in Pcall to find any errors.
            local success, message = pcall(function()
                wait(3)
                PlayerData[plr] = HttpService:JSONDecode(DataStore:GetAsync(key));
            end)
            if not success then
                print('Error: '..message)
            else
                print("Good.")
            end

        end

    plr.CharacterAdded:Connect(function(Character)
        print("LOL")

        RagdollModule.EquipAccessories(plr, PlayerData[plr]["KnifeEquipped"])
        local Humanoid = Character:FindFirstChild("Humanoid")
        if Humanoid then
            Humanoid.Died:Connect(function()
                if GetIndex(CurrentPlayers, plr) ~= -1 then
                    table.remove(CurrentPlayers, GetIndex(CurrentPlayers, Player))
                end

                wait(4)
                if plr then
                    plr:LoadCharacter()
                end

            end)
        end
    end)

    print(plr.Name.." has joined")

    local Level, Alpha =  LevelModule.GetLevel(PlayerData[plr]["XP"])

    --// Print Player Data
    print(HttpService:JSONEncode(PlayerData[plr]))
end)

Script Now (when solved):

game.Players.PlayerAdded:connect(function(plr)

    local key = plr.UserId

    plr.CharacterAdded:Connect(function(Character)
        print("LOL")

        -- DATASTORE IF STATEMENT INSIDE CHARACTERADDED.
        if DataStore:GetAsync(key) == nil then
            --// New player data;
            PlayerData[plr] = Default_Data 
            print(HttpService:JSONEncode(PlayerData[plr]))
        else
            --// Current Player Data; Wrapping in Pcall to find any errors.
            local success, message = pcall(function()
                wait(3)
                PlayerData[plr] = HttpService:JSONDecode(DataStore:GetAsync(key));
            end)
            if not success then
                print('Error: '..message)
            else
                print("Good.")
            end

        end

        RagdollModule.EquipAccessories(plr, PlayerData[plr]["KnifeEquipped"])
        local Humanoid = Character:FindFirstChild("Humanoid")
        if Humanoid then
            Humanoid.Died:Connect(function()
                if GetIndex(CurrentPlayers, plr) ~= -1 then
                    table.remove(CurrentPlayers, GetIndex(CurrentPlayers, Player))
                end

                wait(4)
                if plr then
                    plr:LoadCharacter()
                end

            end)
        end
    end)

    print(plr.Name.." has joined")

    local Level, Alpha =  LevelModule.GetLevel(PlayerData[plr]["XP"])

    --// Print Player Data
    print(HttpService:JSONEncode(PlayerData[plr]))
end)

And even then it doesn't Print Line 12 for the Script(when solved) Is this a roblox error? Or is is just me scripting wrongly..
