Players using a salvage hammer on a large (or small) stocking end up with more stockings (reported in #issues.) Salvage hammer doesn't remove it from the wall.
The same stocking can be shot to 0 health and still be there. The wall can be knocked out and it is still there floating in air.
A stocking that is shot to 0 health can be destroyed IF a salvage hammer hasn't hit it.
Possibly goes on a server reboot?
