Weld breaks when used on opposite player

[SarventeSvendor]

You can write your topic however you want, but you need to answer these questions:

1. What do you want to achieve? Keep it simple and clear!
   I want it so it attaches 2 players together with a weld while playing an animation

2. What is the issue? Include screenshots / videos if possible!
   The animation breaks when the opposite player attaches it
   

3. What solutions have you tried so far? Did you look for solutions on the Developer Hub?
   I’ve search on the dev forum and the only solution I found was to make them massless but it doesnt work

After that, you should include more details if you have any. Try to make your topic as descriptive as possible, so that it’s easier for people to help you!

Any help is appreciated because I dont understand what I’m doing wrong here.

Found out I just needed to anchor the player to fix it. It works fine now
