I haven't had any issues yet, if they don't click when you crush them, they tend to slip, so I would redo them, i pull them everytime to the point I think they would slip and If I pulled the granny out of it, I think that it would snap at the crimp
But I also think if I made a knotted version of my boom if i pull it hard enough it will probably snap, I seem to remember doing that with some fluorocarbon rigs and snapping them someone told me not to pull it so hard 😂
