I believe this bug is fixed in the latest
patch.
If you still have the current game going, you can try using an area effect spell that does not need a target to see if you can force the death animation to end. With any 2 of Frost on a weapon, Stun on a weapon or the passive Stun skill, enemies could sometimes hang in mid death animation and not drop any loot, or give experience, IIRC. Using Hell Spikes would force the end of the animation in this case, but I don't know if it also works on the Demon of Lies when killed by a scorpion or summoned creature.
BTW, you find out what happened to the babe in Beyond Divinity, no need to wait for DD2.
