The lootable bodies mod doesn't play well with other death related thing in the pack.
White Stone: doesn't even activate.
Soulbound: does nothing.
Last Stand: keeps you alive but still strips you and puts all items in a body so you probably just die again.
Void Chest: it collects items you drop in the void, but if they are in a lootable body it all gets deleted.
There are some other death prevention type things in the pack that I didn't try, but I imagine they are similarly broken. I ended up just disabling the mod.
