Weld tool broken - Easy weld works fine

I can weld things and they work fine - until I physgun them. Then the weld falls apart like it’s not even there. I can smash one of two welded props using another prop, flatten it into a pancake - weld stays. It’s only when I touch it with the physgun that the weld dissappears. In rare cases the weld actually stays and on gamemodes that aren’t sandbox or darkDM the weld tool works perfectly fine.

Nevermind, fixed it. Turned out Wenli’s tools was/is outdated.
