When I equip a tool, it flips me upside down. Why?

I am building a 2nd version of my Cafe. I've started putting in the tools/models now and the cups don't seem to be working. Whenever I equip it, it teleports me to some random spot on the map and flips me upside down. I have a model of the cup in the workspace and a tool connected to it ServerStorage. The script for the click detector goes as follows:

script.Parent.MouseClick:Connect(function(plr)
	game.ServerStorage.Cup:Clone().Parent = plr.Backpack
end)

It works in my other cafe, so I'm not sure what to do. Ask me if I need to provide anything else.

Edit: Solved it myself, no welds needed lol.

You can use Weld plugins to weld models together or you can use this https://www.roblox.com/library/181259635/qPerfectionWeld-Perfect-welding-for-EVERY-situat / Place it in your model and it will weld everything together Then unanchor every part in your tool and you will be good to go.
