Have you checked F9 to see if there’s any errors? Have you tried cloning the tool server side? It’s most likely happening because you’re cloning it client side.
I tried with other tools and it works, but when it comes to this umbrella tool, it doesn’t work.
I can’t really help you unless you either give me a file to reproduce this, or diagnose it and give me any errors you see from F9.
Thank you for all the support guys! I have found the problem, the problem was with the Massless property being true. Don’t know why, but when I disabled Massless property, my umbrella works.
I strongly doubt this was the proper solution to your problem. Try re-evaluating your code to see what might’ve really caused this problem.
Woops, forgot to mention it was client-sided stress. 
Gotta eat all that scripting knowledge!
When I changed other tools in the shop’s parts to massless property, it also happened. But I also doubt it is a proper solution, it is temporary fix for now.
I’ve got a number of tools in my game with parts set to massless, they work fine. I’m glad you figured it out, that’s some strange behavior going on.
The tools I have all uses meshes in the part. The problem might be Massless+Mesh, that might do something, you guys try to replicate and see. It happened to me, either a bug or strange behavior.
It would help if you attached a file to reproduce the error with the tool.
