Your OnComponentHit/Overlap probably doesn’t return bone name (or also location) for Characters. It’s not Gore Kit, you should remove for now node “Try to Dismember” for the test and use “Print String” for example, to see if you get all 3 required parameters (actor, bone and hit location). That problem with solution might be related to yours. If you will still have problem with this, I’ll play with it a bit later.
