My housemate reports Buckets of Health are consumed when using herb bags as if it was a herb bag.

Damnit!

I can confirm this. I bought a Keg of Health for some hefty 650 coins, used one of its fifty charges, an wham, it disappeared. This happened during the Dunwarren Staircase quest, but thankfully, the kind DMs already gave me a money refund. Still, it would be great if those kegs wouldn't disappear upon use!

These should work properly as of v820.
