When you die, any items that have the Soulbound enchantment on them don't end up on you, your corpse or the ground next to your corpse.

Without Lootable Bodies, Soulbound works fine, and without Soulbound, Lootable Bodies works fine.

I'm happy to also report this to the Cofh Core developers, if you think I should.

What does cOFHCore have to do with this? So far you've not explained or mentioned how that mod fits into this equation.

origin of the enchant in question - this is a bug in Lootable Bodies and is on the list for research and possible fixing when I finally get time for the complete rewrite

CoFHCore provides the Soulbound enchantment.

It's proving pretty fatal on our current server, where everyone has enchanted soulbound onto all their best items, which then vanish when they die for the first time. I personally had every high end Astral Sorcery item vanish, which must have taken me a week of playing to make - very discouraging.
