Was wondering why the message never came up to be able to feed on corpses anymore. Was fighting necromancers and figured maybe they weren't considered human. Tested this buy killing someone in town and still couldn't feed on their corpse. Hypothesized that maybe the ring broke when I accidentally dropped it out of my inventory. Confirmed my suspicions by loading old save, killing someone in town and option came up to feed. Then dropped ring on ground, picked it up and equipped it and lost ability to feed on corpses after.

so either load back hours of gaming, or continue on with out it... sigh...
