Not sure if this's a bug.

I found an ordinary Healing Kit +1 from the Dunwarren Children quest, in a mephit drop.

Never seen Healing Kits on EfU, so I began wondering if this might actually be a bug in the random loot script. I haven't used it yet, and if it is a forbidden object, I can throw it away.

Old-style healing kits should now automatically transform into medicinal herb bags when acquired.
