Hello.
We have been testing this on our end but we were unable to reproduce the issue -

Was the body fresh (just died) or had it been dead for a while before you saw the floating attachments?

Did you witness the death, or walk up to an already-dead body?

Was anything affecting the body after death (vehicle, explosion, body against a wall/object)?

Reproducible on demand, or seen once?

Characters shot dead on a MP session of conflict. Happens all the time.
Shoot them and very often this happens when you walk away from the bodies. If you play the game you're gonna see it.
