Dummy falling with network ownership issue

[VZNZach]

Hey there I’m facing a small issue with network ownership and client side velocity. I was making a combat system and stumbled on this issue: When setting the network ownership of the dummy to the attacker’s character, it’s causing the dummies to tip over when colliding slightly with them, such as in the reference, that issue doesn’t happen with normal player vs player since other players have clients…

How I set networkOwnerShip :

local rootPart = target:FindFirstChild("HumanoidRootPart")
if not rootPart or not rootPart:IsA("BasePart") then return end
rootPart:SetNetworkOwner(attacker)

How I handle knockback velocity on the client

function KnockbackHandler.applyKnockback(params: KnockbackParams)
    if not (type(params) == "table") then return end
    if not (typeof(params.target) == "Instance" and params.target:IsA("Model")) then return end
    if not (typeof(params.direction) == "Vector3") then return end
    if not (type(params.force) == "number") then return end
    if not (type(params.duration) == "number") then return end
    if not (type(params.verticalForce) == "number") then return end
    if not (type(params.isCasterAdvance) == "boolean") then return end

    local humanoid = params.target:FindFirstChild("Humanoid") :: Humanoid?
    local rootPart = params.target:FindFirstChild("HumanoidRootPart") :: BasePart?
    
    if not (humanoid and rootPart) then return end
    if not (humanoid:IsA("Humanoid") and rootPart:IsA("BasePart")) then return end

    local knockbackForce = params.direction * params.force
    if params.verticalForce > 0 then
        knockbackForce += Vector3.new(0, params.verticalForce, 0)
    end

    if params.isCasterAdvance then
        knockbackForce = -knockbackForce
    end

    local attachment = rootPart:FindFirstChild("RootAttachment") :: Attachment? or Instance.new("Attachment", rootPart)
    local alignPosition = Instance.new("AlignPosition")
    alignPosition.Mode = Enum.PositionAlignmentMode.OneAttachment
    alignPosition.Attachment0 = attachment
    alignPosition.MaxForce = math.huge
    alignPosition.Position = rootPart.Position + knockbackForce
    alignPosition.Parent = rootPart

    local vfxHandler = VFXHandler.new()
    local knockbackVFX: KnockbackVFX = {}

    local maxVFXDuration = 0
    local groundDuration 

    if params.force >= 25 or params.verticalForce >= 0 then
        groundDuration = if params.force > 30 then 0.5 else 0.1
        maxVFXDuration = math.max(maxVFXDuration, groundDuration)
        local groundVFX = vfxHandler:playGroundVFX(params.target, groundDuration)
        if groundVFX then
            knockbackVFX.groundVFX = groundVFX
        end
    end

    if params.force > 30 then
        local trailDuration = 2
        maxVFXDuration = math.max(maxVFXDuration, trailDuration)
        local trails = vfxHandler:playDashTrails({rootPart}, trailDuration)
        if trails then
            knockbackVFX.trails = trails
        end
    end

    if next(knockbackVFX) then
        activeKnockbacks[params.target] = {
            vfxHandler = vfxHandler,
            groundVFX = knockbackVFX.groundVFX,
            trails = knockbackVFX.trails,
            cleanupTime = os.clock() + maxVFXDuration + 0.5
        }
    end

    task.delay(params.duration, function()
        if alignPosition and alignPosition.Parent then
            alignPosition:Destroy()
        end
    end)

    if activeKnockbacks[params.target] then
        task.delay(maxVFXDuration + 0.5, function()
            local knockbackData = activeKnockbacks[params.target]
            if knockbackData and os.clock() >= knockbackData.cleanupTime then
                if knockbackData.vfxHandler then
                    knockbackData.vfxHandler:destroy()
                end
                activeKnockbacks[params.target] = nil
            end
        end)
    end
end
