Welds breaking?

Hey! I’ve been trying to weld specific armor to a basic rig for hours but nothing seems to be working. I was told this was a ROBLOX glitch is this the case?

Im not really sure, this is probably not a good idea, but try using motor 6D (also why is the character being pulled to the armour rather then the amour being pulled to the character?)
I feel like the problem is that the character’s rigs are having higher priority then the amour. Try instead making the amour be welded to the character
